furry tongue

Hello, I have this issue for more than 2 years now (or as long as I remember). It really makes my life horrible, I went through several doctors but nobody can identify the problem. I got checked for viral and bacterial infections. All negative. I am also bloated a lot. I tried almost everything.. even doing the master cleanse (the first photo is just after that) and liver cleanse (which always seems to clear my tongue for a couple of days afterwards but then it 'grows' back). Went to see 2 acupuncturists but they didn't seem to know anything at all about this. I read whole books about TCM and tongue diagnosis, but didn't come to a definite diagnosis. And the condition is so rare that nobody seems to know the answer :/ Do you have any ideas on what it could be? I really need to get my health back finally. Thank you very much! http://i62.tinypic.com/2nq73nk.jpg http://i58.tinypic.com/24183kl.jpg
