It's hard at first but it's definitely worth the effort of going cold turkey. After a month or so the next time you try a soft drink your stomach will feel all gassy and terrible and the drink itself will taste pretty bad.
Or at least that's what happened to me. I used to drink 3-4 cans of pepsi and maybe 1-2 of mountain dew every day. I went from that to nothing and two months later I had the above experience. I've had soft drinks maybe a half dozen to a dozen times over the past year and it's never a particularly pleasant experience.
I've quit soft drinks cold turkey on a few occasions. I've gone from drinking them almost exclusively to having none for months at a time.
My experience was that they were even better than I remembered them. The only thing that I can relate to you is that if I haven't had a Coke in some months, drinking a large amount does upset my stomach.
