GAPS protocol in ED Recovery

“I’m in active recovery from bulimia (no behaviors) and i am doing GAPS protocoL. I am looking for anyone who can tell me if there are negative health impacts to this i should be aware of (other than the obvious horrible mental impact its having on my recovery since it is so restrictive) I have seen countless dietitians and nutritionists and this is the latest and mst restrictive suggestion ive had so i must question whether it will actually help. I have very extreme chronic digestiv eissues and this seems to be the end of the line as far as trying things so im desperate.
