It's true. I'm now caffeine free. It's pretty awesome actually. I sleep better. I don't find myself dragging out of bed in the morning. This hasn't completely rid me of all my UT problems, but they're pretty minor at this point.
As others said, the hardest thing is finding something non-caffeinated to drink when eating out. Restaurants don't tend to carry caffeine-free coke, for example. I don't mind drinking water most of the time, but sometimes I want something with flavor. I'm drinking decaf coffee in the morning, which I know has traces of caffeine, but hey, I like the taste.
I highly recommend doing this. I feel kind of like a different person.
