I think it really doesn't matter the specialty, that first year is a real killer, easily the worst year of your life. I remember how confident I was telling someone who'd already "been there done that", that I would just get up a tad earlier to at least read a little. Hooboy! What fiction that was! But I must say, that Audio Digest tapes for the car did give me a few pearls. It was about a half hour of driving time well spent. The rest, forgetaboutit!
Just hang on for the ride and survive it. Others have, you will too.
Good luck to all the newbies gearing up to begin.
