Hey warrior, I have this symptom too. And it is so hard to go to sleep. My heart races, then slows down, skips beats and sometimes feels like it literally 'jumps' up in my throat. I would definitely suggest getting it checked out though it most likely is just one of the terrible symptoms of anxiety disorder. I have had all the tests done on my heart and I am completely healthy. Hopefully this will make you feel better. I find that I have to completely distract my mind from what is going on in my body in order to overcome it. I try to do the breathing exercises though sometimes it is very hard to focus. I take Valerian (an herb, you can get it at Wal-Mart otc) at night before I go to bed but I make sure to drink a big glass of water and make sure I have eaten cause it can cause heartburn, thus making me freak out even more! lol I hope I have helped you. Let us know how you are doing. God bless you... panicinID
