I'm like Liz - I can't eat any cereals, they all have too much sugar for me.
I can't eat anything with more than about 12% sugar with any safety. I have to read labels really carefully!
Sometimes I dump when I eat carbs, too. If I have dumped once in a day, I stand a greater chance of dumping again that day or the next, it seems - sometimes on random stuff. It doesn't happen much now, but I will have to always be aware of it.
