I am on it also. But can t seem to be off of it for long. Any stress, and my BP goes up and stays up, so I am back on it. I ve only been off of it about 2 weeks in the last year. I reduce my dose if my BP drops too low. I seem comfortable with it between 97/67 and about 107/77. I increase when it gets too high. This works well for me. This is with my doctors permission, and since I have a blood pressure monitor at home. I take either 25 mg, about 37 mg, or 50 mg. The 25 mg pills have no effect for me. I use the 50 mg tablet, and cut it in half for 25 mg. For about 37 mg, I cut the 25 mg half in half again, so I take a half and a quarter tablet, twice a day. Buy a Blood Pressure monitor, and pill slicer. Also be sure to take it with food. For me, it seems ineffective if taken without food.
