brain chemistry and caffeine

[kismet09]

okay, so I was off of coffee from Sunday through Wednesday. Yes, that's four more days than I usually go without coffee. But that doesn't explain why, after half a cup, I'm HYPED UP. Like, fast heart beat, want to go out and mow the grass or go hunting or something. No good at ALL. This must be how the boy feels when he has a shot of espresso. But me? Come on, people, I have averaged 1.25 mochas per work day for the past, oh, five years or so. Four days' hiatus and this is what I get? Freakin' virus.
