Thanks for the reply!!

Tussigon may very well be what our vet gave us for Riley--I can never read her handwriting, and my husband took Riley in today because I had to work. I did read her note that was with it though, saying to give a child's portion of Robitussin.

I did read about the vaporizer too, we don't have one.

One thing that I really think is aggravating it, is them sleeping in the bedroom with the air conditioner on--they are at their worst in the morning.
