Im struggling with sleep deprivation. I have no trouble falling asleep (~9 pm), but I wake up every morning at 3 am and my mind starts racing. And Im in a constantly sleep deprived state. I have not been able to come up with and apply a model at 3 am which will make me go back to sleep.
Thoughts that are racing through my mind at that time: are all the things I need to do when I wake up, or re-playing events from the day before. Eventually I give up and figure I may as well work at that insane hour, but am tired / sleepy / groggy all day.
What do I do? Do I need to run models in the day , or when I wake up in the middle of the night. How do I calm my mind and go back to sleep?
