When i was in high school looking at colleges and trying to decide if i wanted to be a musician or not my band teacher told me that the only people who should be musicians are people who could not be talked out of it. Coming from a medical family, i think medicine is very much that way. If long hours COULD scare you off then you probably shouldn't do it. Even famliy practice docs with decent hours have to have a certain level of intensity to be really good at their jobs. A kind of intensity that would make long hours a RELATIVELY small concern. Concerns such as hours, mean attendings, too much school etc. should really not be the focus of your decision on whether to pursue medicine or not. On the other hand, you can, and will, find plenty of people who'll tell you i'm nuts. Get an extracurricular medical gig (ER, EMT, hospice, etc.) and see if it really turns you on.
