I have this strategy when I go on long drives - consume enough caffeine to stay alert for the trip but not so much that I'm an incoherent gibbering wreck when I get home. Being able to sleep sometime in the next 48 hours would be good too.
I got my plan half right.
So I'm safely home but twitching and drooling more than I'd like. My brain is sorta like radio slightly out of tune with a channel. Lots of static that occasionally almost forms coherent sounds that make some sort of sense. I think I'll run around outside and chase cicadas for a while.
