I got my results from the stool culture after just a few days and it was negative for C-diff or anything. The next step suggested was the colonoscopy but honestly I am feeling a lot better this week and am hoping this will continue. I just can't believe the pencillin could do this much harm and it has been two months to get to feeling better. Still taking the acidophilus and Bentyl (does this make anyone else nervous and not able to sleep?) Anyway wish me luck that this is resolving and I really thank all of you for the information and support I have received here.Diane
