Hello
You may have more luck posting this in the psychiatric medications forum. It helps also to put the name of the possible meds in the title.

Do you know if they are all benzos (benzodiazepines)? That's a type of med that is often used PRN for anxiety. However, my pdoc refused to prescribe me them because they all have a major potential for addiction and it's easy to become dependent on them. But when we started taking me off Effexor, which has horrible, terrible, awful withdraws, she prescribed me one, lorazepam.
Anyway, you probably didn't need to know all that. ohh well

Good luck, my friend!
