I was taking lisinopril and as far as my blood pressure goes, it worked great. However, after taking this drug (and Diovan and Benicar as well,) over time I developed Gastritis and GERD. I've switched to Micardis recently. Day 5 today and I don't get the sharp stomach pains I would get 20 or so minutes after dosing Lisinopril. IMO blood pressure is important to control. There's 100's of these type of drugs out there. I suggest to keep on trying different ones until you find one that works for you. This is number 5 for me (I tried Tekturna, which did not give me the digestion side effects, but was not effective for my bp.) I went with Micardis next because it's formulated differently than the Diovans and Cozaars and Lisinoprils, and so far so good. Wish me luck.
