Wake up time?

I wake up at different times every morning. It all depends on how tired I am and how late I went to bed. There are mornings when I have errands to do so I will have to get up early (I got up at 6:50am this morning and only went to bed at 4am.) But usually, I wake up after 930am. Waking up before that just seems to disagree with my body AND mind.

I wake up at 7.20 when I have to go to college. 7.40 on a saturday. And I don't set my alarm on a Sunday, I just let myself wake up whenever my body thinks it's had enough sleep! It's good to have at least one day a week where you don't have to set an alarm I think.

I work midnights so my bedtimes abd rising times are various from day to day. It's very hard on the system to be honest.
