You go on a soda binge

You get this thirst and only a cold soda will dissolve it. And then only for a bit. You start drinking over 30 sodas a day. You get to the point that caffeine can't pep you up anymore, yet if you stop you will have a horrid migraine. You are stuck on the soda express and the train it won't slow down. Your stomach's lining is being eaten away by the double threats of caffeine and caramel coloring. You vomit several times a day and by now you are having a hard time standing up on your own.
