I just went out and bought seltzer water. That stuff is awesome! Who knew! Charm apparently.

I'll have to pick up some of the Robitussin on my way home from treatment tomorrow. I also thought about using mucinex, but was told by my RO not to start it during treatment. Some mucus is good because it helps protect the throat during the actual treatment. I see him tomorrow after I finish and I'll ask about the mucinex again and about robitussin.

Thanks guys for the suggestions! You're all so helpful!
