Hello Aerogirl, I also went to Dr Huitt and she believes my Mac is caused by silent reflux too. Getting the reflux under control will help with the Mac. On another forum someone suggested a good book you can find on AMAZON called the ACID Watcher Diet. It is by Dr Aviv who is the Clinical Director at the Largest US Swallowing Clinic. They said the book was a lifesaver. I just purchased it and am starting the diet.
