The whole white coating on the tongue is such a tricky symptom though.
Sometimes when I'm on a new treatment which supposedly has some way to help out my tongue, i tend to "see" the problem getting better, even though it might not be.
Since I'm not exactly sure what triggers this problem in my tongue, its very difficult to know whether or not something is actually working, or maybe you just WANT it to work, so you see less of hte coating.
I just went and checked though - the coating on my tongue is definitely thinner and less dense. Let's hope this keeps up. Try the tofu ieatworld, I think this guy was onto something.
P.S. You have to get RAW tofu, not fried - just plain tofu. This guy also told me to stay away from fried foods, you might want to do the same since we have similar GI symtpoms
