I gained about 15-20 pounds since starting, which wasn't a bad thing. Except that I wonder sometimes what the hills are like if I was at my earlier weight ...

But the oddest is how my driving has changed. It's hard to put your finger on it, but the priorities are shifted on the moment by moment decisions. Being happy to go slower in the right lane instead of zipping around and moving in, being more smooth and compliant with traffic, that sort of thing.
