Last year my resolution was not to drink any soda. I actually did it, not a single soda throughout 2005.... then I chugged a Pitch black mtn dew about 1 minute after 2k6 hit. 
This year I'm gonna continue with no soda, and I added no chips or cookies as well.
Isn't it amazing how little you miss soda? I haven't quit outright, but the cutback has been drastic, having gone from 40 to ~53 ounces a day from maybe a can or so a month pretty much over night. Yet I don't really miss it.
I hear ya. If it's your goal to totally blow your body's ability to deal with sugar, overindulging on soda is the most efficient way to do it. What a stupid waste of your lifelong health, especially since it's so easy to just walk away from. I wish the soda jerks wouldn't push it on kids so fanatically. I wish they'd drink water as their basic beverage instead.
I was never anywhere near as much a soda-drinker as many people today seem to be, especially the youngsters, but I still had my fair share over the years. I cut back on it years ago when money was tight, and I have missed it only seldomly. Since then I usually only drink it a couple of times a month, if even that. My last soda was last week; one of those Jones Holiday Pack Turkey and Gravy sodas. I've still got the other four! (Corn on the cob, broccoli casserole, pecan pie, and salmon. Yum.)
