Sometimes a warm Milo helps.
I'm having issues with my cpap machine mask. When I roll over Sometimes it comes off a tiny bit. Straps are tight. I think there could be an issue with the hose as when I roll over its started making a hissing noise. Husband not thrilled. Little dog who sleeps on the bed. (Don't tell anyone) has started groaning when the mask makes a noise so we are all awake.
