Musings: Where's a good caffeine IV when you want one?

Even so, I'm partial to partaking of my caffeine orally -- by coffee or chocolate; not so much Coke (too much sugar and carbonic acid). In the '90s, when I thought coffee was being too hard on my stomach, I'd spell it (give it a break) by munching on chocolate-covered coffee beans and sipping water -- sort of a cold-brewed caffeine.
