I have been on a CPAP machine since Jan. It was the hardest to use because I am claustraphobic. But I worked through that because I didn't want my hubby to wake up and find me dead. Good news, now I am sleeping better and feeling great.Last night was the first time I sleeped 8 hours.WONDERFUL. I had been surviving on 2 hour naps. So, go for it. You will feel GREAT.:)
