Mothers of reflux babies?

My son is 7months old, and has had severe reflux since birth. He has tried Gaviscon, RInitadine, and now Losec (taken with Gaviscon) as the Losec alone didn't work. I have also tried rice cereal in his formula, cranial manipulation, chiropractors and soy formula for two months, all with no success. I still have constant projectile vomiting. A friend has recommended I try goats milk formula, but frankly I feel I have done all I can, and I'm sick of trying new treatments only to be disappointed. Has anyone tried it with success? Has anyone lived through this and overcome it? My doctor will refer me to a pediatrician on Tuesday if things are no better, but I feel she's left things to go on for far too long, and I was only told yesterday that I would qualify for a child disability allowance for him (which won't be backdated). I am fed up and angry, and just so sick of the whole situation. My doctor told me she was waiting for him to grow out of it, but she now suspects he may have a hernia in his oesophagus as he's still no better. Any stories from parents who've lived through severe reflux like this would be appreciated.
