As mentioned, I had mine done this AM. Took the sedation pill - I was awake, but veeeery relaxed. Had all 4 done, and 2 were impacted. The procedure took ~2 hrs, and there was breaking involved, I got stitches, but the actual surgery/extraction was less unpleasant than a cleaning - thanks to the sedative felt like it took 15 mins. The aftermath is pretty brutal so far - still bleeding and much pain.
P.S. Re teabags - I guess I'll ask the wife and see if that makes me feel better.
