I've had bad gastric symptoms (mostly D) for about 6 months, and my doctors are considering IBS. However it is not daily at all (sometimes I feel fine). And when I know I'm going to have trouble, it is usually proceeded by a few days of exhaustion and dizziness. Does anyone else have symptoms like this? I have also lost ~30 lbs, which i understand is not akin to IBS. Any thoughts would be appreciated...
