I have been with my GF for over three years now and when I think about Medical School it worries me. She will be getting her Ph.D while I am getting my M.D.. I have heard from some med students that Med school is extremely time consuming, and that you lose many friends because they do not understand how dedicated you need to be. Truth is, I don't know how dedicated I need to be. What is the time commitment for Medical school (per day or week)? Does it make sense to be in a serious relationship? To get married?
