An update. So I'm now 18 months post treatment, and it seems my furry-tongue has started to improve somewhat. This *may* have coincided with a recent dental cleaning, but that may only be coincidental, too.

Otherwise doing well, continuing to get more fit, my weight is just about back up to what it was at my third and final chemo, and no, weight gain isn't a goal, per se.

Moderate dry mouth is just something to deal with, and xylitol mints are my saviour. Neck muscle cramping is also just one of those things and isn't a big problem.

Pretty much I feel great!
