I've lost nearly 45 pounds, but since the 40 pound mark, I've been having a lot of trouble with sleeping and my CPAP machine. I'm getting a severely dry mouth at night and the Water in the reservoir isn't decreasing. I think I've started to sleep with my mouth open. I didn't sleep much at all last night and I'm miserable today.

My question: how much weight did you lose before you had to have your pressure decreased, and did you have dry mouth symptoms?

I stopped using mine after I was down about 75 lbs. I did some trials and found I slept just as well without it. I would suggest you talk with your docs.

Simon,

I always sleep with my mouth open which is why I have a full face mask.

I am down 27 lbs since I started the Lap band process but 50 lbs since I got my machine 2 years ago.

I have just recently started waking up with a very dry mouth and waking up with a slight headache which goes away after I get up and move around.

I spoke to my primary care doctor and we are in the process of turning the machine down from 10 to 9.

He also told me that if I wanted to try sleeping with out it I could do that and see how I feel the next day.

Hope you find your answer.

Thank you for sharing your experience, Grandma. My dry mouth actually gets stuck closed, and I have to gradually sip Water into my mouth to release it. But I do wake up with a headache and basically feeling miserable.

I tried sleeping without it but I snored so loud my partner made me put on my mask. I think I've had my machine since 2007. Probably time for a new machine. I have come to dread bedtime.

I got a chin strap to hold my mouth closed but since passing the 80 pound mark I sleep fine without it, no longer even snoring. Remember even thin people can have apnea and if you are still snoring you probably still need it. I would have another sleep study and see if u just need some adjustments or if your apnea is gone

Does your machine have an adjustable humidifier? Mine does and its great. I can up the humidity if my mouth gets too dry. Cdheck with your doctor and see if you can get a new machine.
