I have not had any problems on Lipitor yet. But doc just upped my subscript to 40mg instead of the 20mg. Said at 113 my cholesterol was too high! Two weeks after the higher dosage I had bad gallbladder attacks. So bad that I had it removed. Result of higher Lipitor does? I don't know but I think I am going back to 20mg. I think 113 is low enough.
