My wife SWEARS that I sleep BETTER if I have some coffee in the evening before I go to bed! Usually, as I said above, it's a couple of doubles (usually in a cappa, the milk helps too!). I DO on occasion "skip" the coffee for a day or even two, more to insure that I DON'T have an issue with it. Back when I was drinking WAY too much, stopping DID give me the headaches, etc that excessive caffeine (and then a sudden cutoff) can give, but nowadays, nope, no problems in that area at all... I can just drink water for a couple of days and never have the caffeine withdrawal symptoms!

EDIT: WOO HOO, the 100th post!
