Those are pretty close to my numbers. It's about a 10 minute drive in, or a 25 minute bike ride to get to work. I make it up on the way home, though, when traffic becomes a huge problem, and swells the drive to about 45 mins.

Sorry to hear about your car. They all end this way, if it's any consolation. I donated my last car to public radio.

If your trouble is falling asleep, I wonder if that will take care of itself after a few days? As you get more and more tired, your body is going to need sleep, and if you hit the hay early, I bet it'll oblige you. If that doesn't work, try doing some hill repeats on the bike two to three hours before bed, which does the same thing, wear you out. At least this stuff usually works for me. Good luck!
