the C-PAP is a lifesaver (literally). For years my sleep had been irregular and getting worse (waking every hour or so and never getting any real rest). Had a overnight sleepstudy at the hospital and was diagnosed with sleep apnea. The result was frightening (I stopped breathing an average of 127 times an hour, I was waking up because I couldn't breath) Before I went home in the morning I was fitted and given a C-PAP. It took some getting used to because I'm claustrophobic, but I'm into my second year and I'm sleeping much better.
Good luck
