I have had a medication change from xanax to klonopin at abither doctor s request. I was on a low dose of 1mg xanax for severe insomnia and have been changed to 1 mg of klonopin but getting no relief. what suggestions fo you have? I have used Ambien but it is a hit or miss drug for me and only allows at best 3 to 4 hours sleep after which I feel terrible, if I sleep at all. I have gone 6 yo 7 days without sleep which has resulted in hallucinations. I am desperate for answers but working with my doctor with now no results with the klonopin. This insomnia has gone on for yrars.
