As I have found out more about my problem, please help me if possible. The meds I am taking is Atenolol and Clonidine three times a day. My question is when I lay down or go to bed at night, my BP rises from around 140/80-85 to around 195-200/99. At first I thought this was during sleep. But I do not have to be sleep, and can happen within a span of about two hours day or night. Even awake. I have done a blood test looking for answers. All test OK. Also, I have read that Atenolol and Clonidine are short lived drugs, which I guess the reason I have to take them 3 times a day. Do you have a answer to this problem, and is there a longer acting drug that I could take once a day? Do you think that a Calciun Channel Blocker drug would help me? Thanks for your help.
