In my main job I work until midnight, then when I get home I'm usually to wound up to sleep so I wind up watching TV until about 2 am then fall asleep. Then I normally wake up around 10 or 11. Not today. My phone rang which woke me up and I looked at my watch and it said 5 and I wondered who the heck was calling me at 5 am. No such like, it was my manager asking me about why I hadn't shown up for my second job from 1 - 4 pm and I was like "Wait, what time is it?" Turns out I'd slept solidly for 18 hours. Obviously I was very apologetic, but it was so embarrassing. I haven't slept through a shift since I stopped drinking.
