people get addicted to the caffeine in the soda. Before i moved a few years ago, we had a soda called Ski. I drank it every day, a few times a day. I honestly couldnt stop, if i did, i got really bad headaches and was a total hag to everyone around me. I was told when i didnt drink it, it was the same as withdrawl symptoms many people have on cigarettes, and other drugs.
but i do believe once u stop, u can stop for good. I havent drank the stuff in aout 2 years. I tried a sip last year, and it tasted horrible to me. Thank goodness :] No wonder i got fat! haha
