Other than freaking out and having a major panic attack because Cowboy wasn't allowed with me pre-op the procedure went really quickly and wasn't at all bad.
They medicated me out of my gourd and all I remember was waking up once because I was about to throw up, a side effect of the medication, that passed.
Then I woke up again, turned my head, saw my rib cage on the screen and commented on how cool it was.
