What to do? IMO: follow the doctor's/pharmacist's instructions precisely. In my case we were instructed to only break out the opidoid in the event of severe pain (has never happened to me but I guess it's possible), and there were quite specific instructions regarding it. If you don't end up needing it, dispose of it.

Exactly this. Removing wisdom teeth in particular seems to affect everyone in totally different ways that can't easily be predicted, so doctors over-prescribe and give strict only-as-needed instructions.
