HI, I have had sleeping problems for two years now and one of the main symptoms is that I am very awear of my heart beat and can often feel it in my ears especially if I lay on my side. ( Left mostly) as well as feeling it in my stomach/ diaphragm area as opposed to the heart region. I have both difficultly getting to sleep and staying asleep as most night wake up multiple times with heart beating as if i d had a fright. I usually take some form of antihistamine and magnesium to help sleep and have tried many other sleeping tablets that I don t like taking.
