Karin - plain aspirin is known to be a stomach irritant. The coated aspirins are probably better because they dissolve further down the GI tract and not in the stomach.
I take 1/2 plain aspirin per day for my heart (my Dad had a few heart attacks starting in his 40's) and the doc said because of past family history of heart probs, this would be a good idea. I don't think it bothers me any, but then again, I don't have IBS as bad as some of you do.
