What makes you dump?

Been thinking about the past six months and determining what make me dump carbs or fat or both.  Also thinking about what my gram limits are. Havent really pushed the issue to see what they are.   I havent vomited once. Not ever. My version of dumping is when I have had a few bad episodes of the runs usually within about a half hour of eating.  What are other RNY post ops limits for fat and carbs before you dump?

Milk 2% or higher. I drink soy milk and light cheese and once in a while can handle skim or 1% milk. I also had a few bites of carrot cake with frosting for a special occasion and dumped on that.
