When I was on first shift I got terrible sleep all the time. I HAD to use a 5 Hour Energy drink to stay up with my buddies on Friday nights or else I would pass out way too early.

Now that I am on third shift, I get plenty of sleep. Downside is that I sometimes have a little less time to myself before I have to return to work, but going to bed and naturally waking up is something I never thought I would be able to do again as a working adult. It's totally worth any downside of third shift.
