1. I had a bunch of oxygen drops while wearing CPAP (!) starting at 00:24. Not sure why?! All I can think of is that my nose felt a little stuffy, flow limitations at the time were pretty small, but I think this may still have been it... i.e. lying w/o the mask for a while clogged up my nose. Does that make sesne? I pasted the image of that segment below. The segment w/o CPAP before and after are both segment w/ me in the bed but forgetting to turn the machine back on (w/ mask on face). The second segment w/o machine w/ the many drops is on my back
2. I took some CBD before bed and it made me super tired throughout the night. I woke up at ~3:45 to use the restroom (still 90% asleep doing so) and when I came back I simply forgot to put on the mask, I was so tired. But here's the thing - I didn't have almost any big oxygen drops at all while sleeping on my left side w/o a mask like I usually had...?!
3. Maybe it was the CBD that helped - I had a longer than usual segment w/o nose tickles / mask off events at the end (3h7m). But it's a mixed bag either way if it makes me forget to put the mask back on and I also feel similar to having a caffeine withdrawal crash now.
