We leave in 5 days, never drove before. We are driving 75 straight thru from Michigan. I'm terrified of heights, and get vertigo when I look into the open lobby from the 2nd floor of my office building. We will also be driving thru them at night. I'm worried about it being pitch black and driving off the cliff. Am I being silly? Should I just take done meds and close my eyes while DH drives, lol? Help! :/
