You'll start feeling better over the next week or so. Work in two weeks? Don't count on it.
You will start to feel slight improvement in the sore throat department, but once you start to feel a little less pain, there is still mouth sores, fatigue, weaning off of the PEG, keeping your fuid levels up, keeping your calories up, etc.
Tx takes your body precipitously close to death, in order to get rid of the Beast. A near death experience is not something you get over quickly. Take the time you need...the joys of snot will return...spit, well that's possibly another matter, but it will improve. Meantime, take a few minutes ( or a few hours, if you're so inclined) to go outside and smell the flowers.
I guarantee you, you'll never appreciate their fragrance more than will now after being though what you've gone through
