Since I've started driving long-distances, I've been having a very serious problem that is compromising my safety and others on the road. While driving, I would get incredibly drowsy, almost to the point of sleeping while driving. When I stop driving, the drowsiness would immediately subside.
Eating crap food (like chocolate bars and drinks with a lot of sugar) helps alleviate this somewhat, but I don't want to keep doing this to my body (though today I ate a Fiber One bar and that did me good). Coffee helps a little, but fails in the long run (unless Dunkin' Donuts coffee is weak sauce). The drowsiness also subsides when I turn on the heater, full blast, but only works for a few seconds at best.
Does anyone else have this problem?
