Well, one thing is for sure. If it's your chief year you should graduate and pass the boards. You've come this far, and It's a lot easier to make a big life change with a great fallback plan in your back pocket. If you walk away now, you have nothing -- you won't be able to practice medicine/make money at all. It may be difficult to get into another residency as you have used up most of your training allotment from uncle sam. This way at least you can make a good living while you figure things out.
You might rediscover that you love general surgery after you escape from the hell of residency. Call, ER coverage, clinic, work hours are a much different thing as an attending. Doing a few consults or overnight cases might not seem like the worst thing in the world when you are taking Q6 call from home, possibly with in-house resident/pa coverage, and your daily schedule is much lighter.
There are definitely more lifestyle oriented specialties within GS. Plastics, breast, SICU, bariatrics all come to mind. You don't even necessarily have to do a fellowship. Find a practice with a lot of subspecialty guys, and they might be thrilled to hand you all of their inguinal hernias, lumpectomies, and port placements. Can make a nice living that way without a lot of overnight stuff. Another option might be working per diem. Choose your own schedule, take days off whenever you want, and make some pretty good coin. I've heard of per diem trauma (not fellowship trained,ATLS certified) guys getting paid >2k just to take in house call and be present for traumas. I know of one older surgeon who does minor cases mostly and gets paid by the hospital to be the medical director of their busy RN-run wound care service. The point is there are options, and almost all of them don't involve you working the schedule of a chief resident. More time off, more vacation, less call, and way more money are on the horizon.
