I had top and bottom (and all wisdom teeth) done 7 years ago in August. I still have aches, but nothing horrible. I have a bit of numbness in one part of my lip. I lost 20 pounds (currently at this weight too :D ) on the liquid only diet (I was on the upper end of the healthy range for my height at the start). Be ready for some pain, and discomfort, but it's well worth it.
