I have ADD so falling alseep isn't always easy. Its been so much better the last few years using various stratagies to help me be able to get sleep. Sometimes its doesn't work and I don't get the sleep I need. Last night was one of those nights. In addition to that sometimes like today I also loose track of time and end up driving to work because I didn't plan enough time to ride. Its stupid I hate it when I do that. Anyway, 20 extra minutes of sleep isn't going to matter much. The excercise will invigorate you more than the sleep trust me. If all you need your car for is getting to work ditch it for whatever you can get for it and start riding to work. Worst case scenario is to start walking seriously. I have done it a few times and my guess is our commute is pretty simular in distance. Your car problems are probably not helping with the sleep problem thats for sure. =(
