Hello chefron and welcome to the Oral Cancer Foundation. You have been through alot since dx. I don't think anyone can predict recovery time
in a very precise way. Each of us may react differently to the same treatment? Go figure!!!
All I can add is to be patience. This battle is a life time thing.
Do you have a peg tube in or are you able to input enough orally to maintain your weight?

There have been many days when we all felt like you do now. It passes. We all have to adjust to our new post-cancer lives. What other option do we have?

Hoping for the best for you,

Danny Boy
