Surgery tomorrow - any final advice?

First of all, I want to thank everyone here. I haven't posted in this sub before, but I've been lurking for a few months and this community has done a great job of making me feel informed and not alone (in combination with other resources like thyca.org). Background below, TL;DR at the end.

I am going in tomorrow for surgery. I won't know until I actually wake up whether the diagnosis is thyroid cancer. My thyroid function tests normal, but I have consistently high TPO antibodies and ultrasound shows a number of suspicious nodules and possible lymph node involvement. Endo did an FNA on one nodule which came back benign, but the pattern was so suspicious that he actually called the lab back to ask if they were sure.

I was given the options to wait and monitor, or to do surgery. If I was a couple years younger or a couple years older I might have wanted to wait and monitor, but I'm hoping to have kids soon and I want this all to be taken care of before then. Plus, one nodule is so large that I can feel it during cardio and certain yoga positions, so I'd rather just have it out.

The plan going in is to do a hemithyroidectomy and frozen section biopsy mid-surgery. If there's malignancy in the biopsy they'll do a total thyroidectomy with neck dissection. With my endo's experience with this sort of thing I'm fully expecting to wake up with no thyroid at all. I have my fingers crossed that RAI won't be necessary because, again, trying to have kids soon.

For now I'm just trying to keep a lid on my nerves. I know it's a routine surgery and I trust my doctors, but I've never been put under with anesthesia before and the whole concept of it freaks me out. (I had the option to be sedated when I got my wisdom teeth out and elected to be awake.) I have plenty of pillows, soft foods, and fluids of various viscosities to drink when I get home from surgery, along with a bunch of books to read.

For those who've had surgery already: Do y'all have more any advice or recovery tips to share? Did you find laughing uncomfortable? Comedy shows are a comfort watch but I don't want to hurt myself with laughter.

Edit: Before I said I had high TSH, which was a typo; meant to say TPO antibodies.

**TL;DR: Hemi tomorrow with potential TT & neck dissection; any recovery tips besides pillows, soft foods, and multiple drink options?**
