I think both of you make great points; however, although I agree with SainteLigius's suggestion that Doc84 try her hand at Derm before making a switch, I must caution that his/her points are on the extreme side and not necessarily reflective of the actual truth. Speaking from experience, from having been in the field both in an academic and private setting, Fellowship trained, and having experienced training and teaching in this field, I must say:
1. OBGYN faculty are not as miserable, overworked, nor unhappy as you assert. Unfortunately, the attitudes of a few shape the impressions of many.
2. You can gear your practice setting/specifics to any lifestyle or income you seek.
3. Fellowship was not "grueling"
4. Most of us maintain our sanity, marriages, and personal lives.
5. Almost everyone I know or have known, has been satisfied about their career choice. Those few that were unhappy, often time were the cause if their own unhappiness (refusal to give up solo practice, refusal to settle for less cash in exchange for better life style)
To that end Doc84, I suggest you try your hand at Derm given that 1) it drew you the first time around, 2) it's an extremely competitive specialty that you nicely matched into, and 3) it may seem like the perfect fit for you once you start practicing it. If still unsatisfied, try OBGYN as life is long and a couple of more years at the end will not matter much. Besides, you stand to get credit for most of your intern year.
Best of luck to all of you!
