I am traveling and I have not been sleeping well and I noticed I had a sore throat in the morning. What I have figures out is my (1year old) machine is not giving the same pressure as normal. Has anyone else had this happen?

More info.....

So my wife is still complaining that I am snoring and to be honest most night I get 7 1/2 -8 hours sleep and I still feel tired. Is cpap working correctly? I know I do occasionally open my mouth because I will wake up with a super dry mouth. http://www.socalinmotion.com/sleep/Capture.JPG http://www....
