MS (MULTIPLE SCLEROSIS) & driving

I am 56 years old and was diagnosed with MS 14 years ago. Although I have my exasperation events periodically I am still able to walk and function ok. I was placed on disability only because of my previous profession which was carpenter/contractor. My doctors were afraid of the dangers the tools presented and the fact that I was having trouble estimating jobs in a profitable manner. In all honesty it was just taking me longer to complete the work when I worked alone because of fatigue. So my question is, what are my chances of becoming a truck driver, a profession that I've always admired, respected and always wanted to try? For 14 years I've been doing nothing and I am very bored and feel very useless. I know I can drive as I continue to do so done so and since my diagnosis I have driven across the country and back on a couple of occasions. Just this week, I made a 12 hour trip in one day. Not trying to toot my own horn but I believe that I can, be a truck driver and want to know if there's anyone out there with similar circumstances?
