Burp Surgery Tomorrow!!

Hi guys, I’m 19F and posted a while back on here about my RCPD and everyone told me to see Dr. Bastian—who luckily works 10 min away from me! So tomorrow is finally the day I’m getting the Botox done with Dr. Rebecca Hoesli. Was wondering if anyone has any advice for me prior to the surgery. Also was wondering what the pain is like—I had a tonsillectomy at 13 and I swear that is the worst pain I’ve ever felt (worse than tearing my ACL). Anything would be helpful!
