I have not been diagnosed with anything yet either, but the sleep problems drive me absolutly nuts. There was one night last week where I knew I was not going to get to sleep, so I just went in to work (I have an understanding boss) and stayed there all night, I left at 7am. My normal hours are 8am to 5pm. I am wide awake here tonight, and if tomorrow was not a scheduled day off, I would be heading into work right now, as I feel like I am not going to sleep at all tonight. It drives my wife nuts when I am unable to sleep at night, but then during the day when I get tired enough, I am able to sleep, sometimes she just does not understand that I cant control it. It feels like I am on a roller coaster ride, the only thing I can do is take advantage of the up time to get things done, and rest when I can. Most of the problems I have are when I am at rest, when I am lying down, I can feel my heart pound, which causes me to get lightheaded spells, the only thing that can relax me is to take a nice hot shower or bath, which seems to be the exact opposite of most people here. When I am at work and active, I rarly have any problems. Ugh!!!!!!!!!
