I overslept. Saturday I had to pull a double shift, 7am till 11pm. Sunday I ended up with another, 11pm till 3pm Monday. Since I got a regular amount of sleep Saturday, I was up all day on Sunday and unprepared for a double shift which happened after I arrived. Couldn't keep my eyes open after I got home. I kept myself awake till around 10 when I crashed.
So, long story short, I ended up sleeping like 12 hours.
Work in progress, please be patient.
