I take 3,600 mg/day for fibromyalgia/neuropathy/chronic migraine prevention etc. It does have a calming effect.
I think neurontin can be used as a mood stabilizer.
There are also better meds for sleep than Benzos. I take 150 mg Doxepin and 1 mg Klonopin at night. I don't have to increase my Klonopin dose. I've been on this stuff for years. I was on the Doxepin for quite awhile before they even added the Klonopin.
Also, if I experience anxiety during the day, I don't reach for the Klonopin. I grab some OTC L-Tryptophan. It can be purchased at health food stores. It seems to help. Every time that I have taken Klonopin during the day, I have regretted it. Even 1/4 tablet makes me disoriented, then a few hours later, I'm back to normal. (Yet, I see people take it for panic attacks)
Benzos by themselves are not very good for insomnia.
There are other meds that are used as mood stabilizers, I can't remember what they are off-hand.
Sometimes voicing a concern about Benzos to a psychiatrist can get them to look at different classes of medications.
There are also some meditation tapes which can help.
I like this one:

Most of the ones on the Stop, Breath, Think channel are pretty decent. Stop, Breath, Think also has a phone app.
I hope this helps someone!
