In September, I've got 10 days to see everything I can see from Minneapolis to Portland, OR along the route of Amtrak's Empire Builder. Know anything about these places? I'm looking for some Metafilter reconnaissance about my route. [more inside]
For the past year, caffeine has had a strange effect on me. I drink soda or coffee -- and within minutes, I feel groggy, fuzzy headed, and almost kind of drunk. I get absolutely no stimulating effects. The more I drink, the more fuzzy-drunk I feel. Caffeine used to make me feel wonderful -- awake, cheerful, on-point. I've never drank an excessive amount (2 coffees a day, max). Can anyone explain what might be going on in my brain chemicals?
