Is it normal to have NO dumping after eating sugar?

Oddly enough, I started out like you - with no dumping to help me control my eating - on either sugar or fats. I was extremely disappointed and very upset with the fact that my surgery choice "failed" me (because I went with the RNY over the BPD/DS for the dumping syndrome). Then, after months of avoiding the "bad" foods because I knew my body wouldn't reject them, I went on a "bender" (really, really bad stress and nightmare overload in life) and ate and ate all kinds of bad things (chips, cookies, cake, candy, etc.) - not all at once - just a little here and there over the course of a week or so and discovered I DUMP NOW!!! On all kinds of things: sweets, breads with ANY sugar at all in them, including bran, greasy foods, etc. - Months after the surgery, my intestines and pouch worked together to somehow give me the reaction I was looking for. Give it a little time - it could be you'll be one of the lucky ones who's dumping syndrome kicks in after the pouch and intestines learn to work together. Best wishes for the will-power in the meantime!

Unfortunately i do not dump. he only thing that really makes me sick is ice cream.

That's not enough sugar to dump. Once I ate some peanut M&Ms and got upset I didn't dump. A few days later I had some milk with two tablespoons of jelly and dumped so bad! 10 bites of a DQ Blizzard maybe had 10 grams of sugar. Definitely not enough to make you dump. It takes 30 grams of real sugar to make me dump. 15 grams of fake sugar -- ie High Fructose corn syrup (was in the jelly).
