It's interesting that you mention Behcet's disease, since I get frequent mouth ulcers, but I really don't have any of the other symptoms on that list.

I have been checked for Lyme Disease and pretty much every major disease and vitamin deficiency you can think of. The only thing noticeable that came up was a slightly low Thyroid T3 level, but the synthetic thyroid medication they've given me isn't helping at all. Not like the Ritalin does
