irritable bowel syndrome
"I'm in the military and spontaneously developed stomach cramps and black stool. I had a colonoscopy and endoscopy performed and they saw nothing. For 2 years, I was prescribed Nexium which did almost nothing to help. I really thought I would just have to deal with it.

Then about 2 months ago, I saw the doc again and told him I had read about irritable bowel syndrome on the internet and was wondering if I had it. He said my symptoms matched up and I asked if there was a treatment.

He prescribed dicyclomine. The difference is night and day. I still stay far away from soda, beer, etc. but foods don't bother me as much anymore. I still have black stools when drinking soda, alcohol etc. but I can eat a hot dog or a hamburger now."
