Have you tried Losec???  My son had severe reflux problems and we tried lots of other medications before a friend suggested we try Losec.  It’s normally only a medication given to adults but the doctor was willing to give it a try.  We had to have it specially mixed up at the hospital but it was well worth it.  It stopped all the acid coming up and burning him and he hardly ever vomited after we put him on the Losec.  Ask your doctor if you can get hold of some Losec.

Good luck, I hope she’s better soon
