Sometime in your past did you have a fear of falling asleep? Some times people get this when they were pretty young, and it sticks with them. Try and relax, remember it's not going to kill you. Somewhere on the boards~~panic attacks/anxiety,maybe, there was a excersize to do when this panic feeling starts. It was breath in for 7 seconds,hold for 7, let it out for 7, hold for 7....keep doing this till it goes away. It takes practice too. Kinda hard to do at the beginning, just don't give up right away. The jumping is the body's way of relaxing, try drinking more water during the day and cut way down till you off the caffine an/or alcohol products. I know someone who gets panic attacks and she takes alittle sea/salt on the tip of the tongue when they happen. She's also on the watercure diet. 1/4 teas. of a min. seasalt mixed in a little water, for every quart of water taken in. No caffine, cut down slowly if you do have caffine daily. Gives you nasty headaches to just quit. Also calcium helps and so does magnesium, for muscles. Take it a 1/2 to an hour or so before bed time. That should help.
Do you have any blood pressure problems or adema(swelling)? If so go easy on the salt if swelling is present. Take care, Diana.

Gets some rest girl, you deserve it!
