I went for a sleep study 13 years ago because I did weird crap in my sleep (acting out dreams, talking, sleepwalking). Had the worst insomnia. The fatigue was crushing.
I wish I had sleep apnea. I was diagnosed with narcolepsy. So the only thing they can do is give me stimulants during the day. Oh, and for awhile I had legal roofies... I roofied myself twice a night which was scary as hell. The sleep was great but sometimes it made me puke and if I did, I couldn’t get back to sleep. Or, if I fell asleep in a weird position, you freeze that way and you wake up in pain. So now I take a lot of Ambien. Which I love but makes you dependent.
So I think if there’s a machine that can make you feel well rested, give it a whirl. The consequences of not sleeping are real. And not just feeling crappy. I have friends that have the CPAP and it’s helped a lot.
