150 mg. dose has aided to bring down BP to more normal level. Taken before bed, best readings early morning and then more elevated through day. Huge problem: sleep. When I close my eyes images appear extremely rapidly, like an MTV music video. I am 49. My doctor wants to wait to see if sleep problems back off. I've waited but find dreams are miserable and make me feel depressed while sleeping. When I wake I feel awful. I want off this drug!!!
