soda is tough to stop drinking because the extra sugar and caffeine boosts your body depending on how much you drink. You stopping cold turkey will usually lead to you feeling lethargic because your body isn't getting its usual pick me up. I would try having less soda every week and then lowering that amount each successive week. If you honestly can't stop then go with a 0-calorie version so your not taking in the unnecessary calories but still get the fizz you like.

Good luck
