I should add this neurologist is at Shands Neuroscience Institute in Jacksonville, FL. I have had good luck at Shands (several different depts) so far. Been there for years now. I have also been to Mayo Jacksonville and they confirmed the Erythromycin treatment. When I told my gp of the treatment, his response was: ‘Really? It [the Erythromycin] works for delayed gastric emptying? I didn’t know that.’ Scary, but my point is one of the specialized centers like Shands, Mayo, Johns Hopkins, etc. should pick up on it right away.
