Aw! Dumping sucks major tail, I *think* i had it twice so far - but it was on stuff i am normally acceptable with..I'm very sorry to hear you had to go thru that!
first time was with shredded steam carrots - after i ate i had it comming up on me, and i had to force up the food i just ate so i wouldnt feel the discomfort..
second time was with shredded turkey, i think i didnt chew it enough and it made me quite uncomfortable for 2 hours, so again i had to force myself to hack up my dinner. really gross.
