I take (...wait for it ) 4 mg of Klonopin to sleep, but not because it even makes me sleepy...it helps to keep my nightmares away.
I would consult your dr. if you feel such a strong reaction at a low dose, for sure. I know benzos can affect different people in different ways, and I believe agitation can be a side effect of them. I hope you feel better soon and find the cause of this.
