Sally,

I found this information about the medications used to treat PTSD. As I have mentioned, the only one I use, and only when I am really struggling badly is the Klonopin, I personally don't recommend using it constantly.

Another thing you may want to look into is finding GABA at a health food store, that "may" help as that is thought to be "lacking" in those who struggle with PTSD. It is better to try it when you are "not" on any medications. It may be helpful for you to look into while you are in limbo, maybe it will "help".
