Thanks again guys.
I had a very frightening experience last night in bed. I felt lightheaded all night before getting into bed. I couldn't sleep. During the night I came over in this intense sweat (no fever) with lightheadedness. It lasted a while and eventually passed. Not sure if it was a panic attack, I've had them and they have been very different before. Never had anything like that happen to me before. Hopefully going to see a doctor about it today.
