i used to go to bed early, like 10 o clock when i was younger. then it moved to 7 am, then 3 am, then 12 am. few months ago i was doing the 7 am thing again, recently its just been 2 o clock the latest and 11 earliest. i like it much better.
been going to bed at 10ish and getting up at 4 AM... never thought I would be able to do that. used to be a night owl...LOL
