I am quite fortunate. My first symptoms were in 1977 - optic neuritis. I was finally diagnosed in 1985. I semi-retired in 1997, totally in 2005. I still walk but with a walker now, drive using a left-side accelerator in my van, and keep house. The only MS-related drug I take is Zanaflex. Every day, I am grateful for the things I can do. Do what you can, when you can, for as long as you can.
How many specialists did you see before finding "The One"?
