I've had 3 surgeries, 2 of them were outpatient and the other required me to be admitted for 24 hours.

Getting tonsils out as an adult has a miserable recovery, but I'm much better for it.
Getting half of my thyroid out was an easy recovery, but hypothyroidism sucks a dick. Oh, you don't have my prescription filled yet? Well that's okay I guess I'll just feel like trout and do nothing until you're ready. (This hasn't actually happened yet, but it's a constant fear)
Getting my wisdom teeth out was just whatever. I felt like crap for a few days and life went on, just without constant migraines from the pressure.

Having heart disease and doing anything with anaethesia sucks though. You have to jump through so many hoops so they aren't worried that you'll die on the operating table. Anaesthesia is smurfed up like that though.
