What is this going to bed at 1AM stuff, are you a lightweight now.
Well.. On Thursday I went to bed around 9 am and woke up at 3,30 am. Now I sleep between 1 am and 10 am, tomorrow I go to bed at 7 am (actually on Tuesday) and wake up around 4 pm. Three shifts.
But normally on off days I go to bed around midnight - 2 am.
