I got diagnosed with severe complex sleep apnea (central and obstructive). I spent a few weeks with a CPAP but not dialed into the correct pressure but after my first night of sleeping with a CPAP in the lab to get the pressure correct I woke up and went to work.

I was confused because I felt odd, it took me 10-15 minutes standing on a forklift trying to figure out what the fuck was happening. I finally realized that I was experiencing what being awake was for the first time in my life at 32. I reintroduced myself to coworkers I had worked with for a few years because I had been in a haze for most of my life.
