Everybody is different. You'll hear from some who were immediately turned off by sweets; a few who never liked sweets before but liked them after (!!). And then a year out, people's tastes change again. You just can't predict this.
I have avoided carbs but have tried a few, I'd like to say as an experiment to see what would happen, bowel-wise, but honestly I WANTED them... some crackers, a piece of toast, a few french fries, a bite of hashed browns, more than a couple of vanilla wafers. (There is no chocolate candy in my house or I would have tried that, too.) I was really disappointed that I had no gas or diarrhea, foul-smelling or otherwise. (My poop actually seems to have little to no odor post-DS. I know I know, VERY weird.) I can't eat much of anything so do not fear a full-out binge. What I did notice was that a few hours after eating carbs, I wanted more. Sort of like kicking a drug habit, I just have to stay clear.
