Hi SaraM, Good to hear that Zyrtec is helping you! My stomach blows up like a balloon when I react to something, and it doesn't have to be to something I've ingested. Cigarette smoke is just about the worst for me. I also have the coated tongue and nystatin has helped in the past. I don't feel well on other antifungals which, probably not coincidentally, are listed as mast cell degranulators. I see that a number of masto patients mention candidiasis and taking probiotics, but I've yet to find documentation for this connection. If my TMEP diagnosis is correct, which I believe it is, my skin is a bit of an anomaly (like 1 in 3 million). So don't go by that.
