I started on FM and thought it was a great way to start the year. I happened to be at a site that gave me lots of autonomy, so I learned how to conduct a visit, write a note, present a patient and make a plan. This served me well for the rest of third year.
As far as surgery, everyone always talks about how you should have medicine first. I didn't, and I did just FINE academically on surgery. I was exhausted, cranky, and depressed - but not for lack of knowledge!
