Keep it up man!! I started commuting 16 miles each way 3 days a week last summer - but my scale did not move until a 6 weeks ago when I took control of my intake. There are several great sites out there to help you with this - personally, I am using sparkpeople.com and am dropping 1-2 lbs per week. I log all my exercise and everything I eat or drink. Not on any weird diet or anything but logging everything really helps me to make good choices.
