Yes, Candida can suck, and it can suck for years on end. Right now Candida sucks for you because you allowed it to. You stated that at one point your symptoms had “improved drastically” – but then you “pigged out so bad” and bingo, Candida symptoms again. The entire experience is about the choice between feeling and being healthy or not feeling and being healthy.
Rather than doing the fast again, you could simply commit to the diet 100%, add some strong probiotics and kefir to your diet and one or two good antifungals, and allow you body to take care of itself.
