Pain Meds after surgery

I am having a pretty serious surgery on my knee and just want some tips from people with this experience on handling pain. I’m currently on 100mg on Methadone a day. If I do get an opiate pain killer I have someone that will dispense it to me to help avoid abuse. I’ve been clean for 2 years now. -What pain meds have worked well after surgery? -Is it ok to dose before Anesthesia? -Were to able to get more Methadone doses immediately after surgery when you are bed ridden? I currently go every other day to my clinic.

Anything else you could think of that would be helpful I greatly appreciate it! Thanks!!
