3 weeks til surgery ...what do i need ?

I havent gotten any instruction on what I need for post op care...I have not a clue to be honest.
Any suggestions of things i might need ?

What surgery are you having? Ask your dr's office for their recommendations - mine had a booklet with lots of info.

Also go back and read several pages of posts here - you'll find lots of info posted to help you.

Good luck on your surgery.
