I did the p&b shake a while back. It didn't do anything other than give me constipation.
I've also done parasite cleanses with paragone. They're probably good for targeting worms but they couldn't get rid of my candida overgrowth.
You say you have constant peeling lips which is what I have. Do you also feel constantly thirsty no matter how much water you drink? And do you have thrush (white tongue)?
Are you taking anything topical for your external fungal problems? If not, Iodine foot baths may be able to get rid of the toenail fungus and zinc shampoo could help keep the dandruff under control. As for controlling oiliness, I find that taking vitamin b5 helps with that. I take it as a complex just in case the other b vitamins don't get out of balance.
