October 7 Guest, are you sure you are using your monitor correctly? 138/75 sounds a great reading, but the other one would bring you near to passing out! I've read that 0.9% of Lisinopril users have stomach effects. On one or two occasions I've been part of this 0.9% myself. I started on 10 mg and have now been on 5 mg for a long while. Not qualified to give advice, but if I were you I'd be questioning the 20 mg dosage you have been prescribed. I'm 54, slim and do regular work-outs/hillwalking by the way, with no heart problems to date. Am on Zestril brand.
