Thanks, everybody,
I really think the pain is less already, and the sores on my tongue are healing - I was sure they were the cancer spreading when i first felt them, but the doctor said no. I just wish my mouth did not taste so awful, and since nothing tastes good, toothpaste does not help (actually it burns - even the sensitive kind.)
I think my main problem is sitting at home and being too weak to do anything, and worrying about the next check-up.
I will try Dr Pepper tonight - 3 weeks ago it tasted awful, but maybe it's changed.
