Life Without Dr. Pepper

So, I'm attempting it... again.

No Dr. Pepper for me is not going well (it never does). I've got a headache that is kicking like Jackie Chan and I want to crawl under my bed and hide.

The only reason I'm quitting is b/c it's bad for me... and I tend to drink them like water and end up consuming way too many calories than needed.

Why isn't this easy?
