Been on clonazepam for six years and it's my only drug, since no psych drugs have kept my ultradian cycling in check. Yes, it helps me sleep but I've had to push the dose up, though 2mg is modest by some standards and I only use that dose when I'm seriously manic. Most nights I use between .75 and 1mg. For me, it's also a libido killer, but my wife's attitude toward sex has also contributed to libido going bye bye.
