I have Sleep Apnea.
I was diagnosed about 3 years ago now. I had always had very vivid colourful dreams since a child, but as I got older (and a bit rounder) I started experiencing sleep paralysis, choking and gasping for breath like I was choking. When the paralysis & choking started happening at the same time i decided to go and see the doc, who referred me to sleep clinic. I was tested and had 127 apneas in a 1 1/2 hour period and was told I had a tiny mouth and when sleeping it was contracting.
Got setup with a Fisher Paykel machine, which did the biz for about a year or so but over time I got used to the pressures and had to be moved onto bi-pap & been on that for about 2 years.
At first the mask and hose etc is a bit of a pain and the noise can take a while to get used to it. I still dream but don't have choking any more.
Sometimes I sleep without it maybe 1-2 a month, but feel like crap the day after, so it must be doing something.
