Some years back I went on Prozac. I recently read that it is sometimes used to treat IBS.During the time I was on Prozac I was aware of what a "pain killer" it was and how it straightened out my bowel so that I had "normal" movements with "normal" stool.My discomfort lately has me thinking I want to go back on Prozac just to straighten out my bowel. The problem being the other undesirable side effects - sleep disturbance, urinary urgency that seems to have an enduring impact on the prostate (?), complete lose of sex drive, the host of other possible side effects that did not arise during my use is frightening.Do you have any experience or reference to other drugs of this type that do not have the same bounty of side effects and still improve or eliminate IBS?Frank.2
