I know an individual who was in a wheelchair and was diagnosed as being in the SPMS stage, smoked and drank almost daily, and is now walking with the aide of a cane. While he may claim it was because of the copious amounts of PBR he consumed I believe in all likelihood his "recovery" was due to the natural course of his MS or in fact he may have been experiencing a relapse and not in fact been in the SPMS stage. Something I have seen over and over again, since being diagnosed with MS, is individuals choosing one form of treatment. lifestyle change, etc. and immediately associating any disappearnce/improvemnt of symptom(s) as related to that specific modification. That said I can not see where eating healthy, exercising, etc. would not be of benefit including to PWMS. It will be intersting to see the results of the randomized studies when they finally come out!
