Bad moment
I've had something similar happen that lasted 4-6 hours but didn't start until I gave up sugar and white flour at 4 years post-op. I don't know if it's dumping since it's something I haven't had since my original RNY on 11-14-00. I wasn't clean from 3 months post-op onward. I know some other people who have also had this problem who were not cheating on their diets.
