For me, stuck and dumping are two very different things. I always get stuck food, mostly because I eat too fast and swallow too big of bites. I throw it up and I'm fine. Dumping is unpredictable, at least for me. My insides start to burn, I get a horrible "stomach" ache and feel sweaty and faint. I cannot control or speed up the reaction my body is having.
I've cheated on my plan a few times, like eating a tiny piece of peanut brittle or eating a few pretzels, with no dumping. But I ate three small pieces of pineapple or a little bit of ketchup and had it. My surgery was October 14, 2013, so maybe my experiences are from being new. I don't know...
