Is Klonopin the only benzo that doesn't cause problems with libido and ED? I've been on klonopin, xanax, and now valium, and both xanax and valium killed my sex drive but klonopin did not. Klonopin did make me more grouchy and irritable though and was less effective for anxiety. Xanax and valium also made it hard to get an erection while klonopin did not. Haven't tried ativan or any others.
