I hate it....too many straps...too much air,.....I can only keep it on about 3-4 hours before I have to rip it off and have a belching session....

and yes the only real position you can sleep is on your back....

if you move around the mask gets loose and you lose air.....

and the damn lights on the machine lite up the whole freaking bedroom , so I had to cover the buttons with tape, but it still comes thru some

ugh
