Have you tried Adderall. I know there are a lot of people against it but if you read the side effects, there minimal compared to most drugs now a days and it would most def. help you focus on your driving! If you want to take a more "natural approach" try Maca. It's very good with some good side effects. I've also read that Kambucha has some "focus improving qualities". The point being, if you are going to be on the road, you need to be at 100%. :)
