Hi Sabja,
Sorry to hear about your diagnosis. Jack is T3N2bM0. I think you've gotten some pretty good advice here. You need to give it more time. The reason you're having trouble finding better answers on recovery times is because it's so individual and it's hard to predict exactly how it will go. Even in common things it still comes down to severity.

The drug Gail mentioned is getting good results, make sure you give it enough time to see if it works. Jack's surgeon sent him for acupunture and that really helped him - but I've also heard others say it didn't work for them. That's the problem you are going to run into - finding what works for you.

In addition to what's been posted Jack found that prescription lidocaine jel helped his mouth sores. You're still pretty early out from treatment so I'm not surprised that you are having these side effects. Just keep swallowing and it gets better with time. Start small and work your way up.

Good luck.
Regards JoAnne
