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.
