I had mine done when I was 25 or 26, as I had had almost continuous tonsillitis for over a year. I thoroughly enjoyed the entire thing. No, really!

I remember passing out in a haze of morphine flirting with a gorgeous nurse, and when I woke up I had the amusement of watching two medical staff arguing over whether I should have ice-cream or toast.

I heartily recommend toast, as it takes a while to get used to the new size of your throat and toast is easy to swallow.
Pain-wise, a took ibuprofen that evening, and was back to normal (ie boozing and eating chip suppers) the next day.

Hopefully my next op will be as much fun, but I doubt it (planning the snip to ensure no further froglets!)
