i've jusrt finished working nights, got home at 08:00 Monday morning,
stayed up all day, went to bed about 18:00 then accidently slept until 13:00 the next day, couldn't sleep that night, stayed up untill 13:00 the next day (now wednesday)
slept until 19:00 watched tv until 23:00 gave up on normal methods so took some nitol, slept untill now and got up.
now i'm reset back to a 05:00 wake up but it took some doing.
if you've managed to understand all that as i'm not sure i understand what i've written myself, here's my advice.
make plans for the following day that mean you have to get up at a reasonable time. and make tham plans you can't break. you'll be tired but at least awake during the time of the living!
