I dumped twice in the beginning with my bypass,but dont dump now so have to be calorie concious.I can eat anything now but smaller amounts.BTW dumping makes you feel like death!the second time it happened I was sat on the loo with squits,wretching into the sink, going hot and cold,head spinning and fading in and out of consciousness.lay on my bed and remember kicking of my boots ,the dogs joining me and passing out!It was horrible.Hubby was very worried.
