If I Drink This, I Worry I'll Never Sleep Again

I don't have an easy time sleeping. I need a new mattress and have for some time, but for whatever reason I just haven't gotten to it. The main reason sleeping is hard for me, is that I'm a worrier (although I'm getting better) and it's hard for me to shut my mind down to just go to sleep. I keep hearing about this new product from Coca Cola and thinking, if I drink it, will I be awake forever? It might not even have a ton of caffeine or sugar, but it just sounds like it would keep me awake and that head trip in itself is enough to cause me problems. Here's a review of it from someone else, but if I try it, I'll let you know what I think.
