K uses the Risperdal m-tabs prn. They are the fast melts. We use to use Clonidine as her PRN, I don't know if they make a fast melt?
You can also try Diazapam or Klonipin both are Benzos as well. If the Ativan isn't right. They may work better.

I used Zoloft at one time. It seemed to work well for my sleep and anxiety issues.
