Hi there. I've possibly asked this question before, but here goes again. I am having an intermittent problem of staying awake. I had a reasonable nights sleep but I am now really struggling to stay awake. My O2 sats are 94% on air and my heart rate is 114bpm. This occurs randomly, I can be fine one minute then the next I'm falling asleep without warning. So far, I haven't been able to get anyone give me a reason for it. When I was in hospital recently, the Dr in A&E was constantly having to keep me awake whilst they were trying to treat me. This, unfortunately, is not something that has started since my hospital admission, it has been going on for a while now. Does anyone have any ideas what may be causing it? Thank you in advance. Take care, Richard.
