I have a sleep problem that has been going on for years, and it's gotten worse. When I fall asleep. I'll suddenly wake up with heart racing, gasping for air, slight convulsions of my body,adrenaline head rush,and I yell, curse, and swear,every time. Sometimes I even get up from a dead sleep, with all the symptoms above, and I'll start running around circles in my bedroom...and than lay down again. This can happen 15-20 times a night. Usually it will happen for several nights in a row. But than i'm fine and have no problem, for a week or two. Than the cycle will start over again. And than i'm fine again. What is wrong with me ?? This has driven me to the point of insanity.
