I had mine done, awake thanks to a little bit of valium. They were majorly impacted and broken and I had no problems at all with the operation or afterwards. It cost me about $1000 (though fortunately my medical covered 80%)

IMO if you don't get put out you recover much faster, but at the same time if you're awake they have to go slower so it takes a bit longer. Dr. Ron gave me sedatives to take an hour before the surgery, someone else had to take me in and pick me up. I didn't feel a thing or even care what they were doing thanks to the sedatives. He's pretty heavy handed with the pain killers, proscribed 25 T3s I think I took 1. I recommend aleve afterwards instead, it kept the swelling to almost nill.
