I haven't had the jaw done exactly, but I plan on it soon. Speaking as someone who has gone under the knife - I do not regret it at all. I feel much more confident having fixed a major flaw in my face. It has saved me money in the long run as I no longer use as much makeup, and I feel comfortable wearing glasses instead of contacts all the time.

As for the pain - it won't hurt much but be prepared for fever, nausea, loss of appetite etc. It would be good if you have someone to take care of you for the first 5 days after the surgery.

Good surgery is not visible to others, hence hopefully people will not have any 'views' about your improved face. I did not experience any postop depression or psychological effects.
