It was my opinion before doing it that I would be feeling some amount of pain no matter what I did. So I just followed the other aftercare instructions first - ice it, take ibuprofen, (lightly) swish with warm salt water. The pain was reduced enough that I didn't feel the need to take the opiates.
I definitely get the impression that a lot of people sucked into pain med addiction are not the sort that have had a lot of previous experience with pain. Making it doubly irresponsible to prescribe such highly addictive medications for them.
I'm assuming there were significant kickbacks to oral surgeons from the opioid sales people.
Most of the time it would be generic vicodin and cost under $20 for enough to take for a few days.
