Hi Kimmyb
I'm so sorry to hear you're having to go through this treatment.
I had a total glossectomy, split mandible and a radical fibula free flap surgery in 2019.
I was on a lot of pain relief for comfort, which helped a lot. I do have a speech impediment and I'm very slow at eating, but this is due to having no tongue.
My jaw has a plate in it to put it back together, and it felt a bit weird at first, but isn't too bad now as I don't notice it.
