If you are awake at 4 am, and have to be at work at 7, should you even try to get back to sleep or should you try to do something with your time?

Between the time it takes to fall back asleep (which is nontrivial), getting ready for and getting to work, you’d be lucky to get 1 full cycle in before you had to get up anyway. And IME, rolling the dice on a rem cycle like that is more likely to fuck up my day by leaving me groggy AF than refresh me.
