Coke is the way to go. What's also really good is cola with cane sugar in it. You can find it at yuppie foodie organic shops. I go in and out of Boston for Dr.'s appointments, and to make myself feel better about the trip, I'll go into Trader Joe's to get myself a six pack of cane cola.
One of these days when I'm traveling, I'm going to see a Trader Joe's and check it out. Even though it is an extra 150 calories I'm beginning to think coke is better too. I switched to diet years ago to loose weight. Yeah, right.
