In the last 2 years I can only sleep for 4 hours and then I wake up and it takes 2 more hours to fall asleep and I always need medicine to help me fall asleep. 2 Months ago I had a heart attack and the last few days I am not sleeping well, I wake up after 4 or 5 hours sleep so I try to nap during the day, and I wake up after 2 hours with a headache, racing heart, hot, and exhausted. I am taking Lopressor and Plavix. Can you help?
