Hi, Craig.
Congrats on the end of chemo and the pending end of radiation. The joys of radiation may continue for a while as you go through the healing process. The inside of my mouth turned a bunch of different colors and textures over several months, then, one day, everything looked "normal." OK, no teeth on the right side of my jaw, but I'm not complaining.
Keep that positive attitude. Live well, laugh often. You've got a lot of good things to look forward to.
Ken
