Very common with us! My daughter just showed me her tongue last night — she was just starting to develop it, too. Is your histamine under control? Candida? Usually hitting both of these will eliminate it. Candida is TOUGH, because it tends to come back so easily, and your diet needs to be soooo strict. I’m working on a medication to make it easier for us to rise above this! I’m fiddling with the dosage right now. My daughter isn’t on it yet, and she said, “That is just not fair! Your tongue looks great!” Teen-agers! 😉
