I was doing some work from home today like usual. But I had a sudden burst of sleepiness. Usually, I can't focus because my focus is trash, but today my focus was actually really good until I got sleepy; I literally could not keep my eyes open. I woke up at 4am but crashed around 2- 3 p.m. I took adderall and some caffeine, but that didn't even touch me. I decided to take a nap. My work output was so low, and rather than keep trying to push through, I thought maybe I should take a break?? I slept for maybe 30 min. Now I am taking a walk to the store. I will work later tonight than expected and miss out on free time. Not sure if I made the right choice. What do you productivity experts have to say about this?
