OK, was that the sleep apnea talking, or could I really have CSA as well as OSA? I took a nap earlier because I didn't sleep well. My nose is still healing and crusty, and I couldn't get enough air through it, so after a couple of hours of sleep, I took off my mask. The rest of my sleep, there was some snorting, so that tells me my nose was blocked. My sleep was very fragmented.

In the middle of my sleep, I took a Benadryl, thinking that maybe some of it was allergies due to the mold and mildew because of the bathroom leak, but it didn't seem to make a difference. It just helped me get back to sleep. 

When I was napping, however, I was making a point of breathing through my mouth, yet still suffocated awake, unable to breathe. It really seemed like I stopped breathing, but was that because I didn't have the mask on, or because I really do have CSA? I just couldn't help but remember that the person who tested my sleep apnea mentioned CSA, and then there was the trouble I had breathing in recovery. It seems that if my breathing doesn't stop altogether, it gets very shallow. I can only hope these instances were because of the sleep apnea and nothing more complex. I checked my CPAP, and while my AHI score was 4.3, it listed them all as OSA.
