I am so sorry about your tummy trouble. Get yourself checked for C-difficile bacteria, just in case. I had it once, after a run of antibiotics months earlier for a sinus infection, and before the newer and better test for C-diff was created. I suffered with it twelve weeks, after which time I was hospitalized for dehydration, cramping, and diarrhea, where it still wasn't diagnosed. They thought it was ulcerative colitis. Finally, after a biopsy and the coming online of the newer C-diff test, the C-diff was diagnosed correctly at the beginning of my thirteenth week. There is a pandemic of it going on right now. The right antibiotic cleared it up very quickly. Ironically, what started it also cured it. Good luck.
