I drink soda way too often. I only like Diet Coke, and I know how bad it is, but I still love it. I have given it up quite a few times, the longest being about 6 months. But I always start drinking it again. I don't drink nearly as much as I used to (I used to drink 5-6 cans a day, easily), but I still have it at least weekly. Honestly, the thing that helped me cut down the most is the money - I'm saving a lot of money by not drinking 5 sodas a day!
