+- in the begin / middle of the fast issues may worsten- this is the best it means that the problem is being healed(rooted off the body). The worser it worsen the better being healed. But you will survive no worries))

Hello, Buddy! You may be very surprised but your problem with blood pressure(more likely also with back pain) will be solved by taking long term fast. No less then 25 days on water. I did this way - went into raw food 7. days prior to fast, meanwhile made 3 colonoterapies(to get into fast with clean digestion system, one colonotherapy 2 or3 d day of fast when you are already off food). First 7 days I was taking water, then 7 days complete dry(even no touching the water), the rest days on water. Going out of it is most important part. First 4 days only juices. I took pinaple/apple. (First 2 days juicec should be dissolved with water minimum on 50%). After these 4 days integrate digestion preferably with fruits-veggies-juices(pressed of course), raw food diet, on the second(or better third week), starting to take cooked foods.(like like porrigies amaranth, buckwheat etc). At least 1 weak with no meats. Better 2. I had very similar problem then you. With bp and b pain. This completely healed. I am prepairing to my Iboga experience now(having issue with anxiety and depression). Believe me buddy, just do it. But stay alone all these days you will be very sensitive. Better in nature. If you cant, do your work no problem, but it ll be more difficult to overcome issues that will raise up durin fast. I also no thinking should i do Kambo prior to Iboga(1,5 months left) or not) I had several kambo experiences before as well as 11 aya. Good luck to you buddy! (!Just do it no douts, you will be amazed, trust me).
