Help Kicking the Pop/soda habit?

I used to be a hardcore soda drinker, didn't drink anything else unless soda wasn't available. Probably one of the main reasons I was approaching 300 lbs. When I quit I tried just drinking water but there was something missing and I couldn't figure it out. At first I though it was the caffeine but later discovered it was the carbonation. That's when I discovered La Croix flavored carbonated water. You can find them in the soda isle and come in Lemon, Lemon-Lime, etc and are just carbonated water and flavor, no sweetners. Ozarka also has a similar drink that I also like.

At first it'll be like switching to decaf coffee but I found it to be a good alternative. The carbonation is strong so it still has the bite you've grown used to. Worth a shot.
