PS, personally i have been lucky to have been relatively mildly affected.. after my initial intense megadosing regimen, i basically got back whatever i'm going to get back after the initial dx attack.
there's a book out there called 'black patent shoes - dancing with MS' by a woman from my area.. she does not pursue nutritional strategies but she does believe in working hard to retrain your body and regain any losses as much as possible.
since i got diagnosed i have worked to achieve my level 2 ski instructor certification, and also started swimming laps in order to try to meet the lifeguarding minimum - never had swum a kilometer in my life before that.
first time out, i swam a few laps and my hands went numb so i stopped. after that, i just kept swimming in spite of my hands. even though swimming's great to help stay cool, i still stagger around like a drunk for a bit after i get out of the pool - but it's worth it
my approach: no meds so far - just nutrient-dense anti-inflammatory whole foods, and supplements where needed
