I have been taking Lisinopril for 3 - 4 years. I am 43 with high blood pressure. I often have a light headed feeling/dizziness. My biggest problem/concern is I find it very hard to concentrate. I feel tired often and have a foggy feeling. I have always just written this off to the stressful job that I have. Reading these posts has made me think that this bpm may be the problem. Sometimes I will forget to take my med on the weekends and, now that I think about it, I've felt great on those days. This message board has been a real eye opener. I need to talk with my Dr. If anyone has actually changed to another/more effective BPM - let me know. I have cramps in the legs and feet often too.
