My nurse said I had 172 systolic and then the next day that I had 151 BP. So she put me on this lisinopril.I started with 20mg but after feeling groggy in the mornings was put on 10mg. Two weeks later for a follow up a nurse found I had 134 BP. The doctor concluded that the medication was working. He said people have been taking that for over 10 years without problems and that it was better than Beta blockers. Supposedly this was good to prevent future problems. Well I still was feeling groggy in the mornings and when I tested my pressure with 3 different home testing kits my BP was around 90 - 110. I stopped taking Lisinopril but continued to feel withdrawal symptoms the next day. Funny head feelings and not feeling good. Now I am feeling more normal again. I bought an electronic stethoscope to test my BP myself. There is something fishy about that junk and when you find out Lisinopril was derived from a poisonous snake venom you just have to wonder! I am just saying that for my experience I don't like it and I can control my pressure with better vegetarian diets. My BP went up about 20 points after eating at McDonalds!
