i think it took a couple years to really feel as close to normal as it's going to.
i do not follow a gluten free or dairy free diet. i was on a strict diet for 15 years, including no dairy, prior to dx so the prohibitive approach doesn't sit well with me.
i do have a healthy, nutrient dense, anti-inflammatory diet. i supplement to make my blood levels of nutrients match 'healthy controls' in the research, rather than the typical levels of nutrients seen in ms patients.
hope that helps!
