I use a CPAP machine. I couldn't tolerate the mask as it hurt my nose. I use the nasal pillows and don't have a problem. Perhaps a change in the style of mask you're using would help. Also, the CPAP pressure needs to be set correctly. If it's not set right, you won't sleep well. Sleeping pills for a few nights might help. Could you use the CPAP every other night or so until you get used to it?

Best of luck! It is a difficult adjustment.
