Your body feels exhausted but your mind is quite awake. So you’re exhausted and energetic at the same time. Your joints can kind of feel tense if you’re not moving. Walking is enough but then you can also feel overheated pretty easily. Hours 1-4 were largely uncomfortable for me on both.

LSD gave me diarrhea for a solid 4 hours. I think that’s rare but I felt better the next day than I had in years. Probably something to do with gut science but I have nothing to back that up other than my story here.

You want to go to sleep but the final paper is due in 8 hours and you haven’t started. You are going to write this paper and nothing stops the paper from being written. As you find yourself at hour 4 or 5, well past any joy of ideation, you realize that you must still finish the paper. Caffeine is pounding in your head and you have wrestled the entire day before, now your brain is thinking at full capacity whether you like it or not. Oh it’s not a pain that can be seen but have a migraine and say that’s not real or work a hard day and have to walk more. It’s the hurt of causing your brain to be more active than it ever has. Similar to making someone who plays video games all day hike up a mountain. They’re gonna feel it.
