Only a third year medical student, so I don't have as much insight as a lot of people on here, but absolutely yes. I have only questioned my decision once so far at medical school and that was after a lot of personal stuff and a bad day, and for 20 seconds I persuaded myself that I couldn't do it and needed to quit. Then I had a cup of tea, and remembered everything I love about being on the wards and how lucky and priveliged I am to be in this situation
