I have had several episodes of passing out. I used to have to force myself to get up and go to work. Several times (before leaving for work), I passed out. I had two episodes where I was driving and could feel myself starting to get woozy so I pulled over. One time it happened just as I was pulling into my work parking lot. I got to my office, had to sit there for a while and ended up only working for an hour or so before needing to go home. Another was when I was enroute. Both times I could feel it coming on so was able to pull over. The second time after coming too, I sat there for a while, then turned around and came back home. Fatigue is one of the reasons that I can't work. The fatigue is so intense for me that not working has done wonders in that I can lay in bed if I need to and have (sometimes all day). I have only had one episode since July (which is when I stopped working). I was home and had a doctor appointment. I was trying to push myself through the fatigue, felt woozy and down I went. I called my parents, who live through the trees next door and mom was available to drive me. Whenever I've had those episodes, they wipe me out for the rest of the day. I would suggest talking to your doctor about it, but it's probably like my passing out, there's likely nothing they can do...You won't know until you talk to them though....
