I worked a night shift over my winter break, it sucks.
I'd work from like 8pm to 5am.
I'd go hit the gym after work, get home, PWO shake and bed.
One of those eye covers is a life saver if you're trying to sleep during the day.
If you're working a night job and doing it often, I was working a 40 hour week, just start day sleeping, it's easier to do everyday than just days you're working.
I made decent strength gains over the break, had trouble putting on weight, but that's because it was a manual labor job.
As long as you're sleeping you'll be okay in the short term.
