I have had TSA for maybe a month. I got a CPAP machine as I have OSA anyway. I find that the CPAP machine helps in that when I am jerked awake by the TSA, I don't really feel out of breath and am able to get a deep breath in with the assistance of the CPAP. This usually happens 5 or so times and I fall asleep within 30 minutes. At the moment the CPAP starts at 6cm - I think if I get that increased to 10cm it would be helpful.
It's a very strange feeling. Sometimes I will hover between sleep and wakefulness for ages. It's sometimes actually really pleasant - I don't know quite how to describe it.
I am really curious as to why is started. My feeling is I always stopped breathing for a few seconds as I fell asleep, but up until the past month my brain switched into sleep mode just a few seconds earlier, so it didn't register the need for a breath. Similar to how I don't actually notice waking up when I have OSAs through the night.
I am going to start with KK's suggestions of the Wim Hof Breathing and the running.
Great posts ABC. I started having the same problem 5 days ago. It is impossible for me to fall asleep until I've been up for over 24 hours. I drank a lot of alcohol yesterday and went straight to sleep. Not a good long term solution though!
My sleep hygiene and overall health is terrible. I'm trying to look at this as a positive motivator to improve those parts of my life. I am really worried about this continuing though because it is debilitating.
I'm going to get a trial CPAP machine today - I needed one anyway. Hopefully I am lucky and it will help. I'm also going to the doctor today to get bloods and baseline measurements done.
Hats off to everyone on this forum who puts in the effort to help others.
