I take lisinopril for BP. I was put on 40mg at one point because the blood pressure would not come down. I was dizzy even when I slept. I would close my eyes and the room would spin. So I wound up cutting in half also and the lower doze seemed to help out. Along with the lower doze I decided do more excercise to lower the blood pressure. The excercise seemed to help on lower the amount of blood pressure medicine i was taking.
