I've been reading that some of you take Klonopin once a day at bedtime. Currently I am on Xanax, but I may be switched to Klonopin by my doctor, so I wonder how it works for you.Does the Klonopin prevent anxiety and panic attacks by taking a pill once a day? Or do you also take it as needed when you experience a panic attack? And how well does the Klonopin work for you? If you can compare its effects to the effects of Xanax, how do they differ?Thanks for taking the time to read and respond.
