Hi All, Has anyone ever had the experience of waking up in the middle of the night very light headed and feeling terrible. I have been having this experience lately and it is very scary. It usually happens about an hour after I fall asleep. Last night I woke up feeling like this an within a few minutes my bp was 140/76 92bpm. I am now starting to develop extreme anxiety of falling asleep, which I know cannot be health. Thanks for any experience that can be offered!
