I've never fallen asleep at the wheel but I have made some dangerous drowsy driving moves.
I once blew through a stop sign in a residential neighborhood when I was fighting to keep my eyes open. Another time I drove straight over a parking block in the grocery store parking lot. That cost me some $$$ as I popped one of my tires!
This was pre-kids. Now that I'm a mom, I simply will not get behind the wheel if I feel fuzzy or foggy. I've missed lots of playdates and mommy and me classes but I know it's the right thing to do!
