I'm interested in EM for the long run. To make sure it really is what I want to do I'd like use it as my elective (3rd month). Prior to this I will have had Advanced Clinical Skills and Family Medicine. We've gotten a pretty solid EM education, so book-wise I feel confident. What I'm getting at is, should I do the EM rotation early on to make sure I don't hate it or should I wait (it would be early 4th year) until I've gained more clinical experience? Ideas?
