Be careful with Reglan- can have serious and permanent side effects. My daughter takes a med called motillion, has to get from Canada, but prescribed by USA docs. And approved in Europe but not USA. She will not use Reglan. There are books that should help you choose foods, and you need to learn your own tolerances.

My daughter was diagnosed after multiple instances of vomiting black, undigested stomach contents. She does manage ok now and I hope you will too.
