I have virtually nothing to offer except for some quotes from a Garfield strip (I wouldn't know how to find the comic itself, silly me)
Garfield: How was your tonsillectomy?
Jon: It hurts to swallow.
Garfield: Poor baby. May I have your ice cream?
Or something to that extent. We can use our imaginations.
I assume ice cream helps, but I really have no idea. Maybe anything cold helps, like a slushie or whatever. (rambling)
I'm sure if you looked up stories or advice or whatever about tonsillectomies you'd find bunches. I tend to use Google, Ask. com and Bing.
Good luck with healing, and I hope everything went well. :3
