my sleep schedule needs some major reworking. i am finding it harder and harder to go to bed at a decent hour. with an endless amount of homework and grad school research and gre studying to do, i can't seem to find a stopping place and simply call it a night. last semester, i did a sleep down. basically, i started setting bedtimes and each week i would move up the time 30 minutes until i was going to sleep at 11:30pm every night (which is not too shabby for a college student). somewhere over the course of the summer the bedtime faded away. a couple things i try to do are have tea before bed and cutoff any visual media an hour before bed, but sometimes that's just not enough.
what do you do when you need to sleep but you can't keep your mind off of all the things that you need to do?
