I rarely drink soda but when I do I get it as a treat, and I always get regular Coke, not diet or anything. I went downstairs to the vending machine, they were out of regular Coke so I decided to give diet Coke a try, I've never had it before, I mainly got it because it was the only thing with caffeine in it. There were other options that I like, like sprite, Canada Dry ginger ale, and Fanta but none of them have caffeine.
