I am so glad my wisdom teeth have been gone for almost 5 years now, and I will never have to deal with this again. I didn't read this whole thread, since I feel like there's a new wisdom teeth thread every few days, but --- Boost/Carnation Instant Breakfast is fantastic to get some calories in you if you can't eat. Mashed potatoes and chocolate pudding are also great, I started these on day 2 or so, but my face was so swollen and bruised I couldn't even go out in public for a while. DEFINITELY GET YOURSELF AN ICE PACK, I pretty much slept on it, and it really helped with the pain the first few days. That prescription is a bit insane, I had another oral surgery to remove an abscess a couple weeks later (they found it on the xray) and even then, I only got 5mg hydros for pain (which, for me, was plenty actually).
The t3 thing --- blaming caffeine isn't going to prevent them from giving them to you. I straight up tell them, I'm sensitive to codeine, the few times I've taken it it kept me up all night, sweating, anxious, and didn't take away any pain. So, it's not technically an allergy, but they thanked me for telling them and said there's NO reason anyone should have to deal with a pain medication they react poorly to.
