Oh I can see why one would bend over after eating :-) If you are eating at lunchtime or have to rush out after supper/dinnertime to get your kids to a game or a class....as soon as teh dishes are put away, you bend over to tie up your shoes or put on boots BAM up it comes.....I know the feeling.....
I have found that Zantac works great for the immediate upset...but something prescriptive would be needed for constant treatment.
