Everybody above posted all good stuff. Your experience is very familiar to me as well. Base of tongue started in my tonsils spread to the lymph nodes... Shouldn't this be going faster? What can i do to accelerate the process and all that. As noted above the delays feel huge, but they are really insignificant in the grand scheme of things.

One of the benefits is you can eat whatever you want. Ice cream was a focus food group for me until I couldn't stand the taste of dairy. That may have been an effect of chemo. Not sure what your treatment plan is. Become familiar with smoothie devices. I have a Nutribullet that I still use. Various recipes are out there for all kinds of tastes. Shrimp was a good food throughout treatment for me. It's soft and didn't hurt my throat so much. Funny that at some point chicken felt comparatively abrasive.

Regular walks are good emotionally and maybe clinically. I ran for a while and biked for a while, but eventually just walking kept my spirits up.

Emotionally things settled some for me once treatment started. Just committing to a plan helps. The roughest time for me was oddly just after treatment ended.

I worked through most all of my treatment. I did take a few days off mostly late in treatment usually related to chemo. I think I took some vacation time toward the end because I was just worn out.

It's not a club anyone wants to be in, but you're in good company.
