Hey Mr. T!!!
First let me get this out of the way: there are hundreds of people more experienced than I with this. There.
Please pass this on to your friend.
Two sitters is optimum, sitting is actually very tiring. When you know who will be there with you, encourage (or force!) them to do some Iboga research on their own.
If your friend is doing an opiate detox, your sitters will want to be aware that s/he could possibly have some 'breakthrough withdrawals'. If this is the case, they should be prepared to give some more Ibo. Also, they may feel like shit from the ibo alone, exhausted, maybe with heavy emotions running around, and mistake this for w/d. Your friend may think it didn't 'work', when in fact they will likely feel better in a few days to a week.
If your friend can find two weeks vacation, they will be happy they did. One week minimum, and can I say that again? One week minimum, and that still might not be enough to feel competent to handle the daily grind.
Make sure your friend is ABSOLUTELY honest with you about which drugs they are taking, down to antibiotics and vitamins. The day of tx (I was a nurse, that's medical shorthand for treatment) stay off caffeine. Make sure, going by the half life, that the opiates (if opiates) are out of the system. I have a friend who knows far more than I about this, if it's an opiate w/d and you want to know more, let me know, and I will ask about your friends particular situation.
You may want to have xanax on hand, maybe some soma. I've only had experience with the xanax, but what I've heard is that both can help with muscle twitches, anxiety and agitation. I hear those can happen.
Your friend will want to take vitamins, too. I'm sure you've read this already.
You want to start on an empty stomach. It is probable that you will be puking. Get a bucket, the ataxia makes it hard to get to the bathroom.
You may be very sensitive to light and noise, you may want a fan on you, you may want to make a playlist of many hours of music that will be supportive or even driving your experience. A friend of mine listened to *techno* lol. Myself, I like 'space music' all tonal, no drums.
You may become very sensitive to scents.
For me, cleaning my whole house, including windows, was a big deal. It put in my head the tone of renewal, cleaning, refreshing, all that. It was symbolic as well as good smelling.
You will be down for awhile, showering beforehand is a good idea, maybe on many levels.
Make a list of why you are doing Iboga, then be prepared to surrender to the experience.
There's so much more, but there's a beginning.
I am very, very happy for your friend. I know that Iboga can seem so hard to find, and so far away.
Two weeks! Yay!
Love and knuckles,
B
