Sorry. I responded in the manner I interpreted the poster's question (with regard to my own explanation of my interpretation of "potency" as described above), especially considering that Klonopin was no longer being effective for them.
The only benzos that are still prescribed exclusively for anxiety relief and that available to most people in pill form are Klonopin, Xanax, Valium, Ativan, Librium (Valium's older brother), Tranxene, and Serax. I don't have any experience with the latter three (except for the fact that Valium metabolizes into Serax, aka oxazepam), but they're all relatively old. I'm not saying they're not worth a shot, but I can't help but think that you're looking for something strong and fast-acting, which is what led me to my original suggestion of Xanax. Valium is fast-acting, but it metabolizes into two other benzos that are generally only used as sleep aids (temazepam and oxazepam), so I don't know if that's what you're looking for or not. I've never had the chance to try Ativan, so I can't give you any help on that one.
I didn't mean to be presumptuous.
