Staying FIT: Addicted to Soda aka Soda Junkie

Okay so this may sound ridiculous, but I LOVE LOVE LOVE drinking soda.  I am a total soda addict and or junkie!!!!  I drink soooo much soda and I know it is unhealthy for you and can add on weight.  I am trying to drink water, milk, and orange juice instead.  It works...But I still crave SODA> YUCK I know.  I would love to hear your tips on what to drink.  I used to drink diet green tea and I found that the "fake" sugar made me crave sweet snacks...I still drink diet green tea sometimes.  I thought if I changed to drinking soda that I would be able to do it in moderation, but I can't seem to do this.  Should I go COLD TURKEY?  What are your thoughts?  What do you drink?
