Hey guys, thanks for the input. It's nice to see that this is not an isolated problem and that it does happen to normal people although I'm sorry to hear that it has happened to yous.
It took a lot for him to bring this problem to me , and I have been trying to learn as much about it as I can, the vitamin and allergy problem is new information I have not found any of that info anywher else.
I will pass the info on to him and see what he thinks, as for now I will help him hide what ever manuevers and detours he needs to make in order to deal with this, even though they are costly to him and the company.
Maybe I'll just throw him in the truck with me for a few days and show him how to cross these thigs at 95 miles an hour while drinking coffee, smoking and talking on the phone, that might straighten him out, then he might think that driving himself even white knuckled across them is a piece of cake at 55 mph. LOL
