I'm on night shifts, so I oddly sleep better in the day than at night so slept really well. Though I generally sleep well, my issue is actually falling asleep. If I'm not tired enough then all bets are out, I'll just be lying there for hours trying very hard to fall asleep. On night shifts I'm already tired when I get home so I fall asleep fast. I get my 8 hours of sleep that way. Oddly enough, even in the summer months when I get home and sun is already out, it's not really hard to sleep. I never had to worry about installing a black out blind or anything.
