high blood pressure
"My MD wanted me to take Lisinopril rather than Lotensin, for some reason. It sure worked well in lowering blood pressure but the side effects were a pain in the neck.  I was taking 20/25 mg and was dizzy, headachy, awfully tired all the time, stomach upset, aching all day in my feet so that I could hardly walk, as well as other side effects.  On my own I cut it down in half and feel much better. My blood pressure is still on the low side, but these miserable side effects have finally let up.  Guess I'd better tell the doctor. "
