Showering before the morning ride has worked for me, too. I end up showering twice on bicycle commute days (before the morning ride and after the evening ride home). I'm not crazy about showering twice a day, but it is offset by all the great benefits of commuting by bicycle (fitness, weight loss, save gas money, no miles in a car, etc.). I haven't tried the wool suggestion yet, but plan to do so at some point. Keep at it and try different things; you will find what works for you.
