I'm down to pretty much rice and coconut. Is there a special diet for bad acid reflux?

Several. There are several diet changes that can help with reflux and some of this can depend greatly on the person. Some people will get reflux with certain foods that never bother many others. Would recommend you call your physician for general advice specific for you. Certainly can decrease tomato paste and acidic and spicy foods in the meantime as a trial. Also try to eat regularly/not skip meals.
