TT Surgery Scheduled. Advice, tips? Experience after Surgery Info.

I have a surgery date of March 26. I am incredibly nervous. I keep having the thought that I'm taking away something important and if it doesn't help make me feel better I can not put my thyroid back in. So please share your success or no t success experiences with TT. Also any tips and advice? Do I need a special pillow? Certain foods? What to look out for? Thanks in advance. Wishing you good health.
