I am in much the same boat as Doohickie. We just moved this summer and the commute went from 9 to 15 miles each way. All of the points Doohickie mentioned I have noticed also. One thing that helped me is to pay attention to eating after getting to work, this helps greatly with the ride home. I think you will be fine, besides this is the response you really wanted. Get the house and enjoy the ride.
