Okay so I have been drinking Pepsi and Coke for years now and I really want to give it up. Only problem is, if I try to, I get headaches and feels SO run down. Cola just makes me feel happy. I think I could be addicted to caffine. I drink about 1-2 litres a day. Anyway I want help/tips on giving it up. Can anyone recommened any other healthier drinks or foods that give you the same alertness that caffine does? Thanks!!

It always happens. When you give up something that you have been addicted to, your body starts going crazy. But all you have to do is endure through the crazy period, after a few days (or weeks) your body will adjust again and you'll be fine.
