have you been tested for Candida albicans? You can also do a simple spit test that gives indication of whether you have infection with it

Many people with fibro, GIT probs etc have it and get much better when it is cleared. Also evidence that people with MCS may have rampant candida infection
you may want to check on that
btw a good place for these kinds of health questions is usually the General Health forum

I am moving this post there cos Social Forum really is meant to be a place where everyone can take a break from illness related stuff
