I am underweight too. I started doing the B&P and the first thing that came out was worms! I later discovered that my Oregano complex has Wormwood and Artemesia but I only took them for 4 days. I am starting to wonder if my problem is not Candida so much as parasites. I am waiting to pass some serious plaque, then those parasites are gonna be blasted to Hell... Imagine, I am taking all these expensive supplements just to feed the internal zoo.
Oh, and I am eating more than before, 3 good meals a day. Sometimes my lunch is potato chips with humous but even that is better than my old diet of coffee and a packet of bisquits.
I was also scared to do it. So I started with 1/2 tablespoon for a week, sporadically. Go as slow as you want but GO!
