I woke up with a wicked hangover this morning. Strange, because last night I imbibed no alcohol. So how did I get so dehydrated?

I ate some thai food (pineapple red curry) and drank two cups of Gevalia coffee over at Aaron's, whereupon I proceeded to repeatedly piss like the proverbial racehorse. I understand that caffeine has a diuretic effect, but I drink a lot of caffeine normally, and that day had consumed less than normal (cursory research indicates Gevalia does not have an abnormal amount of caffeine relative to other coffees). Googling "curry diuretic" yields 43,500 claims as a diuretic.

Maybe it was the combination of the two?
