Before the Session: Preparation

The Day Before

• Confirm your treatment space is ready (see our safety guide for the full environment checklist)
• Avoid alcohol for at least 24 hours before your session
• Get a full night of sleep—fatigue can intensify side effects
• Review your provider's instructions for your specific dose and protocol
• Let a trusted person in your household know you will be having a treatment session

The Day Of

• Fasting: Do not eat for at least 3 hours before your session. A light meal 4+ hours prior is fine. This significantly reduces nausea risk.
• Hydration: Drink water throughout the day, but stop drinking 30 minutes before taking your dose.
• Medications: Take your regular medications as prescribed unless your provider has instructed otherwise.
• Blood pressure: Take a reading before your session and record it. If your reading is above 160/100, contact your provider before proceeding.
• Set an intention: Many patients find it helpful to set a simple intention for the session, such as "openness" or "relief." This is optional but can enhance the therapeutic value.

Right Before You Begin

• Use the restroom
• Put on comfortable clothing
• Silence your phone (but keep it within reach)
• Dim the lights or put on an eye mask
• Get into a comfortable reclining position
• Have water, an emesis bag, and your blood pressure cuff nearby

During the Session: What You Will Feel

Taking the Dose (Minutes 0–5)

Place the tablet or troche under your tongue as instructed. Most providers prescribe a sublingual hold time of 10–15 minutes. Let the medication dissolve slowly without swallowing. You may notice a slightly bitter or medicinal taste—this is normal. Try to stay still and relaxed during the hold period.

Onset (Minutes 10–25)

Effects typically begin 10–20 minutes after placing the tablet. You may notice:

• A warm, relaxed feeling spreading through your body
• Slight heaviness in your limbs
• The beginning of a "floaty" or detached sensation
• Sounds may seem distant or slightly altered

This is the dissociative effect beginning. It can feel unfamiliar during your first session. Remind yourself that this is expected, temporary, and part of the therapeutic process.

Peak Experience (Minutes 25–60)

The peak effects of sublingual ketamine typically last 20–40 minutes. During this period:

• Dissociation: You may feel separated from your body or surroundings. Some patients describe it as observing themselves from a distance.
• Altered perception: Time may feel distorted. Visual patterns or colors may appear with eyes closed.
• Emotional processing: Some patients experience memories, insights, or emotional release. This is considered therapeutically valuable.
• Physical sensations: Tingling, warmth, or a sense of weightlessness are common.

Coming Down (Minutes 60–90)

Effects gradually fade over 20–40 minutes. You will start to feel more grounded and present. Motor coordination returns slowly. Many patients describe this phase as peaceful or reflective. Stay reclining until you feel steady enough to sit up.

After the Session: Recovery and Integration

The First Hour After

• Sit up slowly when you feel ready. Test your balance before standing.
• Drink water. You may feel thirsty.
• Eat a light snack if you are hungry—something simple like crackers or fruit.
• Take another blood pressure reading and record it.
• Many people feel calm, clear, or emotionally lighter. Some feel tired. Both are normal.

The Rest of the Day

• Do not drive for at least 4–6 hours after your session
• Avoid making major decisions or signing documents
• Keep physical activity light—a walk is fine, intense exercise is not
• Avoid alcohol for the rest of the day
• Journaling about your experience can aid integration

Integration

Integration is the process of making meaning from your ketamine experience and applying any insights to your daily life. Effective integration practices include:

• Journaling: Write down what you felt, any thoughts or memories that came up, and how you feel now
• Therapy: If you are working with a therapist, discuss your session at your next appointment
• Mindfulness: Meditation or breathwork in the days following treatment can extend the therapeutic window
• Rest: Give yourself permission to take it easy. The brain is doing important work in the hours and days after treatment.

Tips for the Best First Experience

1. Start with low expectations. Not everyone has a profound experience on the first session. Therapeutic benefits often build over multiple treatments.
2. Trust the process. If dissociation feels uncomfortable, remind yourself that it is temporary and part of how ketamine works.
3. Music can help. Many patients use calming, instrumental music during sessions. Your provider may have specific recommendations.
4. Have a sitter if possible. Especially for your first session, having a trusted person nearby (not in the room, but in the house) adds a layer of safety and comfort.
5. Follow your provider's protocol exactly. Do not adjust your dose, timing, or frequency without consulting your clinician.

When to Contact Your Provider After Your First Session

Reach out to your clinical team if:

• You experienced significant nausea that lasted beyond the session
• You had a panic attack or severe anxiety during treatment
• You felt no effects at all (your dose may need adjustment)
• You noticed mood worsening in the days after treatment
• You have questions about your next session's timing or dose

Good providers welcome these conversations. Dose adjustments after the first session are common and expected. For more on dosing, see ketaminedoseguide.com. If you are considering switching from your current provider, switchfromjoyous.com has guidance on transitioning safely.
