Nothing worse then being buzzed all night watching infomercials.
Yes there is. Spending all night on this site in the hopes that some interesting threads will develop can be pretty bad. Especially with caffeine. At least the infomercials make every possible attempt to gain your attention.
I never drink coffee. Just never developed the habit or the taste, I guess. But chocolate covered coffee beans are pretty good. Those are especially bad, though, if one just keeps picking at them....
I try to stay away from caffeine since it just makes me jittery as hell, and like I want to crawl out of my skin. For me, that bad feeling ranks right up there with "I want to do something, but I don't feel like doing anything."
