Caffeine
I seem to be odd… Smart-assed comments aside… I just returned from drinking a double-long-espresso and I’m falling asleep.
Caffeine just doesn’t seem to affect me the way it should. I think for me it’s psychological: coffee in the morning wakes me up, at night it puts me to sleep.
Probably a dose/tolerance thing, but strange none-the-less… I mean, how many people do you know that’ll fall asleep while in a cafe drinking their 3rd or 4th large coffee.
