I can only speak for the adnoid removal, but I know you will get a good response on the tonsils too.
Removing the adnoids was outpatient. We went home relatively fast. The recovery wasn't terrible. He seemed uncomfortable, and the tylenol with codine that they gave us helped a ton, when he would take it. He is usually great about taking anything, but hated taking this. Must have tasted horrible. What I finally did was, I got a little sippy cup that wasn't spill proof and he would take a huge suck off of it and get most of the dose before he realized he'd been tricked.
Good luck! Keep us posted!!
