Thanks for that info. I'm so sorry you suffer from that, though. But I found it helpful. I actually do also have sleep apnea. My last sleep study showed up to 90 obstructions per minute. It's not weight related for sure. My mom told me she can remember when I was very little having to sometimes stay up and watch me sleep because they were terrified I'd just stop breathing! I have no clue why I was never diagnosed until well into my 30s...
I absolutely hate the CPAP. I never got bronchitis from it thankfully (had no idea!!) but it doesn't seem to help my sleep quality. So I rarely bother. Anyway, that combined with my PTSD makes for pretty shit sleep. That's actually the cause of the major sleep disruptions for me. My flashbacks mostly manifest as vivid nightmares, and I'll wake up in a panic a lot. I'm sure not breathing probably makes a lot of that worse, but I don't really notice that normally.
