It will normally go in P2 because of the lack of sugars and grains, but the detox symptoms can be pretty severe: cravings, headaches, nausea etc.
The more you can do about it before P2 the better I think. The beginning of P2 can be hard enough without the withdrawals!
If you are experiencing any negative symptoms from candida die off I would suggest adding some sort of detox along with it. I believe whenever you can rid the body of an overgrowth of candida it's a good thing. Also try adding some acidophillus too.
