I use a CPAP also and after testing my dr explained that depression and sleep deprivation have the very same symptoms. I was able to very much reduce my antidepressants (those have side effects too that you don't want to have to experience if the CPAP works for you). My CPAP helped me greatly and I hope to eventually be totally free of the small does of antidepressant I now take (and taking that small does only for the stomach discomfort I have associated with anxiety). Good luck to you and God bless -- sleep deprivation is the very worst thing to rob us of our energy and thus our sanity!
