Christine makes some great points. Sometimes, we may feel we can drive, in the midst of treatment, pain meds, etc., but take the extra step of having a neutral 3rd party evaluate your driving abilities. During that time and the last 3-4 years during my decline, I have a friend that is a private investigator and ex-law enforcement officer ride with me through rush hour traffic to make sure I am as safe as I feel. I try to do it every few months.
We had one member here from Florida that was a salesman on the road constantly. He never stopped working or driving. I think I pushed myself because of him, but safely.
