Welcome to the club Chris. It is my understanding that most people reacquire the ability to eat and drink pretty much normally.
But, however, there are some who cannot, like you and I ,whether it be Mucocitus or Dysphagia, never reaquire that ability.
Even though I am back in treatment (Chemo) I wasn't able to swallow due to both mucocitus and dysphagia before my recurrence.
