The point of drinking in moderation is that sometimes you don't drink in moderation.
Certainly the caffeine in coffee, whether it's Starbucks or generic coffee, is somewhat of a stimulant. But if you drink it in moderation, which I think four or five cups a day is, you're fine.
Drinking bear is easy. Trashing your hotel room is easy. But being a Christian, that's a tough call. That's rebellion.
Moderation in temper is always a virtue; but moderation in principle is always a vice.
