I just stumbled upon this thread, so I hope you have figured out how to manage your symptoms by now. If not, aloe vera is commonly recommended for acid reflux (maybe not by doctors, but by field adjacent providers, and sufferers). It coats and soothes surfaces. I have never been DX'd with silent reflux but from research have decided I have it due to my symptoms, and the fact that the symptoms are mitigated if I do diet and lifestyle changes. The OP got his information from the web site of ENT Jamie Koufman. You can google her and find out more if you are still interested in the topic.
