Venkat, adding my welcome and sorry you're going through all this. I wish you courage and strength.

Many of us myself included survived for months on various commercial brands of liquid nutrition - things like Ensure and Boost and their clones here in the States. Are these readily available to you? I found them indispensable and even now more than 2 years out still use them regularly.

As others have written, the mucositis will eventually go away. It's unpleasant and keeps you awake at night, I know. But hang in there!

Ditto for the dry mouth that inevitably follows. That one generally takes longer to abate, but there are sprays and gels and things to help. Plus just keep water handy at all times.

I was prescribed viscous lidocaine during RT to help numb the sores in my mouth so I could drink. I had a lot of those so it was only marginally successful. Maybe you'll get off with a lighter sentence! Anyway, you might ask your doctor about it.

Try and sleep as much as possible. I could barely do anything but during RT and I didn't have chemo. And keep us posted. We're all in your corner.
