I live in Southside and have recently been getting extremely sick everyday I drive to work. I get this extremely nauseous feeling that almost makes me pull over and wretch on the side of the road. It's really strange, because it happens at the same spot. I'm on 31 heading towards 59N and it hits me...after I get on 59 I start feeling better. Also, it doesn't happen on my way back, just my way to work. I went to the doctor and he really had no answer for me. After much contemplating on the subject, I think I may have found the culprit.
