Before the therapy, it is good to avoid grapefruit and tonic water because it contains quinine. These have an effect on QT prolongation, an abnormal heart beat, which has caused problems during ibogaine treatments.
Ibogaine is also contraindicated in combination with some foods or drinks such as herbs like goldenseal, st. johns wort, and asafoetida.
In the days leading up to your treatment it is a good to modify your diet. That means to avoid fried, fatty, salty, or overly processed foods, pork or refined sugars and carbohydrates. Instead, eat lots of whole grains, fruits, vegetables, fish, and chicken. For five to seven days before your treatment it is advisable to take a B-12 capsule, 3000 mg of Vitamin C, potassium, magnesium and calcium supplements daily, along with one half aspirin.
Hydrate the day before. Drink lots of juice or an electrolyte drink. You should reduce your ingestion of liquids approx. 4 hours before, because it will be difficult to get up and use the bathroom during the initial phases of the session.
On the day of your treatment, eat lightly in the morning or not at all. Your stomach must be empty for the medicine to work properly. It is preferable to aet a bit of papaya before taking the therapy. Papaya will help the absorption of the medicine.
