Congrats on your decision. If it makes you happy and feel better, that's all that counts.

As always, there are two sides to every story. Here is a lady that is 104. She credits her longevity to 3 Dr Peppers a day. All the doctors who didn't drink Dr. Pepper tried to tell her it was no good. Good thing she didn't listen because she outlived all those quacks.

I am another great case. I myself have not drank water in 40 years, I only drink Dr. Pepper. I drink 2 liters everyday. I'm almost 60 and my doctor says I'm very fit. Keep doing what I'm doing.

BTW, according to this study, you are 10x more likely to die of lung cancer than liver cancer you spoke of. Should we all stop breathing too?
