I know I have OSA because I did a sleep study and was diagnosed. I use a CPAP which helps, but it helped much more when I first got it, I think my throat has built up resistance to it. I think I might also have mild narcolepsy because when I go to sleep my dreaming is immediate, I've always been that way, but I've read its normal to sleep a long time before dreaming occurs. Also lately I've had a lot of nights where I only sleep about 2 hours or less.., is this insomnia? Is it possible that I have all 3 of these sleep disorders? And more importantly do you have any advice for me? Thank you.
