Let's Talk About Sleep Apnea!
Since Steph was good enough to ask her question (does air blowing into your mouth from the CPAP make you thirsty) in front of blog and everyone, I figured I would answer it the same way (to be helpful to as many people as possible, of course, NOT because I am a whore for an easy post idea).
Fun fact: lack of quality sleep both increases carb cravings AND SUGAR PRODUCTION. This means while that while my brain was deprived of oxygen night after night I might as well have been downing cinnamon buns, so the apnea probably caused at least part of the weight gain, rather than the other way around. Am I bitter? Only a little. (Only a little my fat over-sugar-producing sleep-deprived ASS)
Eve actually just got a referral for a sleep study, because people say she looks like me and my doctor said this might indicate that she has similarly small airways (sorry for passing on crippling anxiety and malformed airways, Sweetie).
To answer the question about the mask, air shouldn't actually be blowing into your mouth. There are some masks that cover both the nose and mouth, but mine are actually called nasal pillows and just fit in the nostrils. If the CPAP is working properly, you should be able to breathe exclusively through your nose. In fact, I find that I am thirsty in the morning the nights when I don't wear the mask, especially if alcohol was involved. When I was pregnant and the apnea was at absolute peak - I'm talking scaring small children three houses away - my tongue would feel like a dry stick rattling around in a stony cave in the morning.
Of course I did sort of hope that starting to use the CPAP would automatically make me a chipper morning person and I would lose thirty pounds. That hasn't happened. But I don't wake my husband up sounding like I'm dying several times a night anymore, and that's a nice thing. I'd like to think my brain is grateful.
