My personal experience with CVS has had no dietary related symptoms, however, I have heard from many others that diet is very important to controlling their CVS. Some people swear that going vegetarian or even vegan has worked wonders for them while others simply stay away from fats, sugar, and dairy. We should all eat a healthy, fresh, whole foods diet and while this may or may not control CVS symptoms, it's certainly a good idea to try. Just remember that CVS is a neurological condition, not a gastroenterological one so diet may actually have no real effect.
