i too am having trouble using my cpap machine..they gave me a new type of mask that doesn't cover your face you stick 2 tubes up your nose and strap it to your head..it is ok for a short time and then my nose starts to ache-- also the vent to let out air is very loud. they came and adjusted it and i don't know.. i am so tired of using the machine but do know that i need it...so tired all day and somewhat awake thru the night. the dr gave me provigil 200 mgs and it helps some but co-pay is expensive so i don't take them everyday. usually when i have appts to keep. then he increased it to 250 by taking another half later on in the day.. helps but not great.. i feel my depression also stops me from using the cpap...at times i just don't seem to care much anymore.. good luck with all...using it at least part of the time is ok at least you are getting some decent sleep once in awhile.... moonstar
