I dont know the answer to your question but I would go slow, quiet and with no hurry.
One have to discover carefully if his body, mind and will can tolerate and sustain such a drastic process. Kambo is already demanding by itself, why to exacerbate the therapy ? I feel that patience and gentleness are required to balance the vehement power of this medicine.
Just 3 sessions of 5, 7, 9 dots, the next not apart more than 28 days from the previous, would be fine, as the native tradition of kambo teaches.
The three days intensive treatment i guess was invented by G. Lattanzi to optimize the time\costs of his meeting during the weekends...
It happened i discovered, just long time ago, that autoimmune issues could also be effectively cured with a reasonable practice of urinotherapy.
Sananga has nothing to do with your problem: you can spare it for another time, unless you don't like to be tortured just to prove you're crazy enough...
Rapè also could be useful to clean and open the nasal conduct before the kambò, but is not necessary to have it every day. It depends also how much rapè is used: too much is unnecessary sufferings. It lows the blood pressure so one IMHO has to find what\when it is something to be enjoyed and funny, without slip into self-harm.
