Replying to Acl, Mcl surgery coming up

I'm finally getting surgery... in two weeks!

I've never had surgery before apart from my wisdom teeth. Can anyone here that has undergone acl, mcl surgery or both give me some tips. Not looking forward to the recovery but I know this surgery needs to get done and I'm ready to put effort into the physio and recovery. I also purchased a pricey cryo-cuff
My surgeon already gave me a pamphlet with some info but I want to hear from you guys who have had the surgery and what your experience was like!

-How bad is the pain after the surgery?
-do's and don'ts
-Any Tips?

Thanks everyone?
