It drives me crazy when people crow about being "special" -- "I hate cilantro, it tastes like soap!" -- but this is an area that's always kinda weirded me out:
I can drink a triple espresso and be deeply and refreshingly asleep an hour later.
And I'm not claiming that caffeine doesn't work on me. Far from it; that scenario is nightmarish. Much like my dead gay son, I love my caffeine jolt, and a world in which caffeine had no effect on me is a world in which I wouldn't want to live.
It's just that when it's time to sleep, caffeine doesn't keep me awake, and so far as I can tell it doesn't make my sleep any less restful.
What's up with that, Piratecat? (Hey, that rhymes.)
