I had heard about the sea salt thing that Karen had mentioned too! I'd try that!
My daughter had reflux very bad and up until about a year ago was on prevacid. She's almost 5 now and what we do for her is give her orange juice and she doesn't have any more trouble! It is exactly what the gastrointerologist said to avoid but it works! Someone had told me that usually people with reflux don't make ENOUGH stomach acid so adding something to their diet that is acidic actually helps. Some people take apple cider vinegar every day, so that's another option.
Good luck! I hope you can find something that works for you! I hate having my kids on medicine because they CAN cause reactions like that and it's very scary! Let us know what happens! :o)
