I had the same issue and still do on some days.
I followed dietitians orders and found a Protein I liked before surgery and afterwards, I hated it! They made me physically I'll and I couldn't keep them down.
I will vomit up and entire meal if I eat too quickly, eat the wrong thing, or don't chew enough. This happens more than I'd like. I have issues eating at the table with my family. I find myself eating at their pace and by that time (even if only 3 bites in) it's too late and I will be sick. They say never to eat near the tv but it keeps me focused on something other than the food and I eat slower that way. Actually, I'm eating right now and this post helped me pace myself....so, thanks! Lol
