I took .5 mg of klonopin every 12 hrs (1 mg per day) for 4 months. After not getting the results I wanted, I switched from klonopin to valium to see if valium would work better for panic attacks. I switched directly over from klonopin to valium without tappering off the klonopin. I immedietaly started taking valium(20 mg per day) in place of the klonopin. I've been taking 5 mg of valium every 6 hours (20 mg per day) for a month now and it doesnt seem to work as well as the klonopin. If I want to switch back to klonopin, can I just switch back without tappering off the valium? Or do I have to taper of valium while re-introducing the klonopin. Any help or advice would be greatly appreciated. By switching back and forth, will tolerance become an issue?
