How soon before/after ACTUAL rad treatments should one do this?

Do I still have time to order the device, learn how to use it, etc?

Or should I just do the tongue depressor trick? (That's what I did following surgery in the hospital to re-learn how to get my mouth open big enough to eat)..Of course, my sister bringing me a pizza didn't hurt either :-)

Actually, the first couple of days, it was torture since I was starving and 'wanted' to eat solid foods so badly, but couldn't...UUgh! I just remember how miserable it was and don't want to repeat this during radiation.

I already am bracing for the mouth and throat sores/pains from the chemo/radiation combo...In fact, I still have some slight discomfort when swallowing since the surgery, like the muscles aren't the same, or something...It hurts a little under my chin when I swallow, almost like how a pulled muscle, or 'charlie horse' feels, but in my neck/chin area.

Guess it's always something
