Medicine in general is a great field, and always will be-- in spite of the politics that you hear
complaining about. As for addiction, my first love truly was anesthesia-- I enjoyed
the career immensely, and it was a huge loss to let it go. In anesthesia, I 'cured' everyone, and occasionally had a very exciting and exhausting case where I knew I made a difference. With addiction, the 'saves' are infrequent, and you never know for sure if you are making a difference.
