Weekend in one day

Worked an 8 hour shift friday and then wen I finished at 6:00pm I started work again and did an 11 hour shift through to Saturday morning.
got home at 6:00am and then at 9:30 had to do 2 more hours of work and again at 3:00pm... then went to sleep for a nap and didn't wake up to 10:00am the next day..... so it feels like a really short weekend..... and I have to do it again next week :-(
