I have been doing ICHD now for about 8 years. I love it so much I am now the manager. Yes, you will get use to the at work by 4:30 am and going to bed when your kids do. It is hard but on your off days, take a nap. I no longer need to be at the clinic by 4:30 except for the days I work the floor. Don't get in the habit of going in extra early, it will only get yourself in trouble. You will have time to get all of your work done during the day if you are good at time management. I still have the problem of waking up early when I don't need to be there early. To sleep in would be a dream. I am up by 5:30 on days I don't work. Yes, I love my coffee.
