I also use Clonazepam (Klonopin). It takes a while to kick in but lasts longer than Ativan or Xanax. Has a more calming effect too. Helps me sleep sometimes but if insomnia is really bad it doesn't work. For agitation with anxiety I use Olanzapine (Zyprexa), the fast release wafers. It really calms me down and is a better sleep aid. If only used occasionally I get no side effects like weight gain.
