HOW MUCH CAFFEINE?

The Wisebread blog, worth reading for its frugal tips, lists how much caffeine is in your favorite drink.

Starbucks (Grande) iced coffee, 16 oz, a personal favorite, has 190 mg with the ice, without the ice, it contains 380mg. Since it's a blog noted for saving money, it also rates the cheapest way to get a caffeine fix, No Doz, at $0.0008 per milligram of caffeine.  (that's $ .15 cents instead of $4+ bucks for the equivalent in Starbucks--minus the ambiance).
