I am sorry there are no responses for you. There are MS diets out there that people feel help. Perhaps you have already investigated. I have tried gluten free; it didn't do anything for me. There's also swank diet as well others. Most of the diets don't really show results for a few years. It's definitely important to eat healthy: low fat, complex carbs, lots of fruits and veggies and water.
I hope this helps. Sorry I can't offer more.
