TL;DR
- •A first sublingual ketamine session at Tovani is a structured 1-2 hour experience at home: settling in with your support person, dosing, a deep dissociative window, and a quiet integration period — followed by a restful evening.
- •The dissociative effect typically peaks 30-45 minutes after the dose and resolves over 60-90 minutes. By bedtime, most patients are essentially back to baseline cognitively.
- •You self-administer at home with a trusted support person (a "sitter") present for the session, plus the KetAI companion. Your physician sets the dose and reviews your intentions and concerns during your telehealth visits beforehand — there is no live clinician on video during dosing itself.
- •Preparation matters: light eating before, water available, comfortable familiar environment, headphones with prepared music, no driving or major decisions for 24 hours.
- •The mood response can be visible the same day — many patients describe "feeling lighter" within hours of the first session, though full response typically develops over the first 2-3 sessions.
- •The next morning, most patients return to normal activity. You're not impaired the day after; the dissociative effect doesn't persist.
Step by step
- 1
The hour before — preparation
Eat a light meal 2+ hours before to reduce the chance of nausea. Set up your space — quiet, dim, comfortable, with water nearby. Have your prepared music ready (Tovani provides curated playlists; many patients use their own). Make sure someone you trust is in the home for the session, even if not in the room with you.
- 2
Settling in (10-15 minutes)
You've already discussed your dose, intentions, and any concerns with your physician during your telehealth visit — there's no clinician on session day. This window is for settling in: your support person is with you, your space is ready, your music and eye mask are set, and the KetAI companion helps guide you into the session.
- 3
Dosing (5 minutes)
Place the prescribed ketamine lozenge under your tongue. Hold without swallowing for 10-15 minutes — the medication absorbs through the oral mucosa. After the hold time, you can swallow what's left. Most patients describe the lozenge as slightly bitter; some patients pre-rinse with a flavored beverage to mute the taste.
- 4
Onset and dissociation (30-90 minutes)
Effects begin within 15-20 minutes — body sensations shift, visual experiences build (saturated colors, geometric patterns with eyes closed), and your sense of your surroundings recedes. The peak lands around 30-45 minutes after dosing and is intentionally dosed to reach a deep dissociative ("K-hole"-level) state — the therapeutic core of the session. You'll be lying down with an eye mask and music; the experience is fully interior. Your support person stays nearby throughout.
- 5
Recovery (60-90 minutes)
The deep dissociation lifts gradually. As it does, you can talk, walk to the bathroom, and drink water — but you're not yet at full operating capacity, so let your support person help if needed. Stay in the comfortable space. Many patients journal during this phase to capture insights or impressions while they're fresh.
- 6
Integration (15-30 minutes)
A quiet integration period — journaling and the KetAI companion help you capture what felt notable while it's fresh. There's no clinician on session day; anything you want to flag (what came up, any concerns, possible dose adjustments) is reviewed with your physician at your next telehealth visit so the protocol can adapt.
- 7
The rest of the day and night
No driving, no important decisions, no alcohol for 24 hours. A quiet evening is ideal — most patients describe feeling reflective and gentle rather than activated. Sleep is typically deep. Vivid dreams are common the night of and following nights.
What this actually feels like
Sublingual ketamine at therapeutic doses produces a deep dissociative state — by design. As the dose builds, the body can feel heavy, weightless, or dissolved, and the sense of being a separate self looking out at the world softens or drops away entirely (a "K-hole"-level experience at full therapeutic doses). Most patients describe vivid visual experiences with eyes closed (color, geometric patterns, sometimes imagery), distance from their usual concerns, and at times profound feelings of compassion, connection, or ego dissolution. Words become unreliable — patients don't talk during the peak; they lie down with an eye mask and let the music carry the experience. The depth is the therapeutic mechanism, and it's held safely by the physician-set dose, the prepared setting, and your support person's presence rather than by keeping the experience shallow. Music plays a major role; many patients describe it as a guide through the experience.
Timeline
First-session response varies. Some patients feel a clear mood shift within hours of the first session — "lighter," "less heavy," "the depression is quieter." Others see initial response after the second or third session. Full response typically develops over the first 2-3 weeks (3-6 sessions). The session itself is 1-2 hours; the medication effect resolves by bedtime; the next morning you're cognitively normal. Patients often describe the days following the first session as a "honeymoon" period — sometimes the response lasts only 3-7 days at first, building duration with subsequent sessions.
Common concerns, addressed
“I'm worried I'll lose control or have a bad trip”
Therapeutic sessions are intended to reach a deep dissociative ("K-hole"-level) state — that depth is where the therapeutic effect comes from, and it's very different from chaotic recreational use. What keeps it safe isn't a low dose; it's the structure: a physician-set dose titrated to you, lying down with an eye mask and prepared music, your support person present, and a time-limited window (60-90 minutes). You won't be walking around or steering the experience at the peak — that's expected — but you're held by the setting and your sitter, and it resolves on its own.
“Will I be addicted to ketamine after this?”
Therapeutic sublingual ketamine in supervised settings has very low addiction risk per published evidence. The episodic dosing (sessions over weeks, then monthly maintenance) is structurally different from the chronic-daily use that drives addiction. Tovani screens for substance-use risk during eligibility consultation.
“What if I cry / panic / have a difficult experience?”
Difficult emotions can surface during sessions — that's often part of the therapeutic effect rather than something going wrong. Your support person is with you throughout, and the deep dissociative state tends to let difficult material feel observable rather than overwhelming. Most patients describe difficult moments as meaningful in retrospect, not damaging. Anything that came up is reviewed with your physician at your next telehealth visit.
“I don't want to talk during the session”
Good. Most patients don't — and at a deep dissociative dose, talking isn't really possible at the peak anyway. The session is interior: eye mask, music, headphones. You discuss everything with your physician at your telehealth visits; during the session itself it's just you, your support person, and the music. Words feel unreliable during the peak.
“What if I have nausea?”
Common but manageable. Light eating 2+ hours before reduces the chance significantly. If nausea occurs, anti-nausea medications can be added to the protocol for future sessions. Some patients use ginger or peppermint preparations.
Who this fits best
Sublingual ketamine therapy works best for patients who: (1) have treatment-resistant depression, anxiety, or PTSD that has not responded sufficiently to SSRIs/SNRIs and/or therapy; (2) are comfortable with at-home telehealth treatment; (3) can arrange the supportive environment (someone in the home, quiet space) for sessions; (4) don't have specific contraindications (uncontrolled hypertension, severe cardiovascular disease, active substance use disorder, active psychotic disorder, pregnancy/breastfeeding). For patients with significant trauma history or prior pathological dissociation, additional clinical screening and possibly slower initial protocols are appropriate.

Frequently asked
Do I need someone with me during the session?
A trusted adult should be in the home — not necessarily in the room with you, but available. They're there for unlikely emergencies and to help during recovery (water, walking around, etc.). Many patients have a partner or friend present in another room with their door open.
Will I feel like myself the next day?
Yes. The dissociative effect resolves by bedtime; the next morning you're cognitively normal and back to your usual activities. Most patients describe the day after as similar to a day after a deep meditation or therapy session — reflective and gentle rather than altered.
How quickly does it work?
Some patients notice mood improvement within hours of the first session ("lighter," "less heavy"). Others see clear response after the second or third session. Full response typically develops over the first 2-3 weeks (3-6 sessions). The mechanism (rapid antidepressant effect via NMDA/glutamate) is fundamentally faster than SSRIs (4-6 weeks).
What if I don't feel anything?
Not feeling anything during the first session doesn't mean treatment is failing. Some patients have a delayed response; others have a subtle response that builds with subsequent sessions. Dose adjustment, environmental optimization (music, eye mask, supportive environment), and patience over the first 2-3 sessions usually produce response. Discuss with your physician if you're not seeing change by session 4-5.
Should I journal during or after?
Many patients find journaling immediately after the session (during the recovery phase) helps capture insights or impressions that fade quickly. Brief notes are usually more useful than detailed accounts. During the session itself, words are often unreliable — most patients prefer to stay inside the experience and journal afterward.
