Hi and welcome to the GERD forum.
First let me advise u, there is not a Dr in this forum, if u look at the top u will see a link to forums which will give u a list of public forums and Expert forums...look under the Expert side to find one where a Dr will answer u.

I am not sure what u mean by u had the surgery....do u mean a Nissen?
If so, I am to understand u can not vomit once u have this surgery....so I am confused as I have not had this procedure.
