Don't be nervous... easier said than done, I know, but as a Suporn daughter, I can tell you they treat you like family, and care for you very thoughtfully. You'll have more than enough painkillers given you as you need them, and his complication rate seems very very low. You're in as good hands as you can be, and when you wake up, you will be elated. Prolly also pukey, freezing cold, or dizzy (haha), but elated. 🙂
