Nelie,

I had something similar happen a couple of months after I finished my treatment. I was scheduled to teach part of a training session (I think it was a 1-hour segment) on a topic that I had taught numerous times before, so I was thinking it would be just like all the other times. For some foolish reason, I didn't even have a water bottle with me! After about 20 minutes, my mouth was toast, and I had to run out and grab some water and try to regroup to deal with the extreme dryness and irritation. Even though it helped a bit to get some hydration at that point, I ultimately had to shorten my part of the session because I couldn't make it the full hour.

It's good that you will have some student interaction in your class -- I'd suggest that you try whatever you need to do to maximize that part of it while you're getting back your strength. Also, is there anyone who could be some sort of teaching assistant with you for some time to help with the lecture portion?
