About 6 months ago my doc prescribed klonopin for me because I was being awakened at night by tremors in either my hands, arm, shoulder, etc. This combination of ambien and klonopin keeps me asleep except for trips to the bathroom. However, if I take a daytime nap, I get lots of tremors and twitches, lately to the point of sometimes even biting the inside of my mouth. I guess this is a symptom of the brain misfiring that Dr. Cheney talks about in the article about Klonopin. I will discuss this with my doc next visit but was wondering if anyone else has this happen to them. It's a little scary.
