Trying to go to sleep and heart rate is 55 - ugh

i did start taking my atenolol at night but it seems that during my menstrual cycle, my heart rate is lower. 

now i can't go to sleep.  stupid i know.  too fast, too slow, i can't ever be happy.  haha 

anyone else do this when you are on your cycle or anytime even? 

a friend did tell me too that his mom died in her sleep for no reason and thinking about this, does freak me out.  i need my sleep!  ugh  

is that too slow?  a week ago it was 90 for 2 days.  geeeeeez.

Hey,
I have the opposite feeling. Often times at night my pulse is 85-95 (I fake Atenolol 50mg). During the day I usually rest at 62-75 (which is ideal for me). I have normal Bp, even before I started taking Atenolol. My doc said my pulse was high but not too abnormal. He put ne on the Atenolol to treat my heart palpitations (pre-Atenolol my pulse would shoot to 120-140 resting whenever I had an anxiety attack. I know it's frustrating to have your pulse or bp not where you want it. I also know about the fear of dying in your sleep, my friend did so back in November. The thing that normally calms me down is looking at the stars and trying to make peace with myself each night. I take Ambien to help me go to sleep.
I would voice your concerns to your pcp and I reiterate if you feel something is absolutely not right, you should go to the ER. I hate paying such a high price but sometimes it's better safe then sorry.
