Have one every month. That way it is not a temptation and you do not make a big deal out of it.

I'm a diet coke addict and the way I deal with it is that I drink half a bottle and keep the rest for latter. The fact that I know that I still have a half-full soda makes me not want to buy another. And if I feel like drinking some soda I just take a sip. The soda is at room temperature so it tastes like shit. This crappy taste makes not want to drink anymore and I can go without buying a new bottle of diet coke for more than a week. Sometimes I can last a month. By using this method I don't feel guilty if every once in a while I have a soda and I've been able to reduce my daily intake of a bottle of soda to just one small bottle (20FL oz) every one or two weeks.

When (mostly) quitting soda I discovered my craving was actually 80/20 carbonation/sweetness, so I could almost totally satisfy it with club soda (cheap) or sparkling mineral water (pricier but generally better). Seltzer didn't work—I think it had too little salt, tasted weird. Lemons and limes are pretty cheap if you want a little flavor and a touch of sweetness, and they provide some vitamins so they're not a total waste of calories. Much better than various flavored sparkling waters, IMO. Mostly I drank it plain, though.

Of course I have a lot more fat on me now than back when I averaged (guessing) 1.5L/day of soda and probably 4000+ total calories a day, almost all junk food. Lots of effort just to slow the progression away from a fit (looking) body toward a middle-aged one. And I feel way, way less healthy and get sick all the time, as opposed to never. Man, being a teenager was great. :-/
