If the commute is getting you down, just get yourself a motorbike and it all becomes a bit more fun. Journey times are predictable, when the traffic lessens you can have a blast, and you'll generally get to work with a smile on your face. I've been doing it on a fireblade for the last 6 years and i thoroughly recommend it.
If it's only a short journey, I'd certainly look to a bicycle, or perhaps a little vespa?
fairly regularly I have to get from the south coast to Leeds and back in a day.... So that's 11 hours of travel before I've done any work. Certainly takes it out of you.
