I quit smoking about a year ago and since then have had HORRIBLE insomnia. I can't fall asleep on my own without sleep aids. When I do finally fall asleep, even with the sleep aids/prescription sleeping pills, I tend to wake up 4 or 5 hours later with my heart pounding for no reason. I had to be put on beta blockers for my racing heart. Without them, my heart rate would be over 100 beats per minute all day. Also, if I exercise, it makes things worse. Any thing that gets my heart rate up such as watching a scary movie, laughing too hard, exercising, etc will cause me to not sleep that night. My doc says it's because my adrenal glands are on hyper-drive since I quit nicotine. Anyone else having these problems?
