The good advice: exercise.
I do calisthenics (push ups, squats, lunges, planks, core, calves, pull ups, anything) post social fatigue, and it… just gets blood to my brain. I dunno how else to describe it. Im not a fitness buff by any measure, but if I do a decent bit, I sleep better and wake up with more stamina too.
The bad advice: caffeine.
It’s easy to get hooked, or drink too much and exacerbate issues (like talking fast/slurring, obsessing, focus narrowing for me), but some coffee definitely helps me. Even over a baseline of not having caffeine for months. And I feel it pairs well with a little exercise.
