ok. first thing i will say is i am a smoker, over weight and have sleep apnia. not a good combo. I go to the dr regularly but haven't been for a few months... for whatever reason my bp is fine at rest, around 120 over 80 but when i sit up its around 160ish over 90. i often get lightheaded. the only time i get lightheaded is when i sit. standing is fine, i feel fine but for whatever reason it never fails if i sit to long. Its also fair to say i have been very, very inactive in past year.
Everytime i go to dr, he says its fine but im at a loss for what to do.
