Sleep apnea can be really serious. My mother and my partner both have it and sleep with CPAPs. My partner says it makes a big difference for him. So go back as soon as you can!

I'm the same way though. Sometimes I just do things on autopilot without even thinking, so then I can't remember what I even did. Nothing huge, but little day to day things. Things like whether or not I put food away, or turned off the stove, or locked the door, etc. It's kind of scary that I can do that stuff and have no memory of it at all an hour later. And it's even scarier that I might forget to do something like turn off the stove.

My mother was on Ambien years ago. She hallucinated really bad and had no memory of it at all. She took it one night, and we went to bed. A little while later, she was knocking on my bedroom door, accusing me of having a party in there without her, and she doesn't even have anything to wear to a party, and what will the Queen think if she doesn't have anything to wear, etc etc. It went on for a while, then she finally got in bed and fell asleep. Another time, she said she woke up and the matches weren't in their usual spot. That really scared her, and she stopped taking it after that. My grandmother had been on it too, and she said she woke up one morning next to an empty Oreo package with no memory of eating the whole thing.
