Yea, still wondering what "vistral" is...hah. What exactly kind of "doctor" are you seeing? An Allergist? General Practitioner? Allergist/General Practitioner?
Sounds like you have a regular doc instead of a psychiatrist, or a dumb psychiatrist. As Mr. Green said, benzos should never be stopped suddenly or without expert monitoring. On the other hand, some people just sail through. The new drug would probably cause drowsiness more so than a benzo, but not necessarily, as we're all different.
I've heard of vistaril...not vistral. Vistaril is given for Allergies though lol. Might have some mild sedative effects. How's the the "vistral" working out?
Welcome to the site. How long where you on klonopin for? To explain. There are 2 types of benzos. Those that kick in just after taken and those that you don't really feel kick in at all. They work over the full day. Klonopin would be a 24/7 form of medication. Normally dosed out twice daily. Thus doing you the full day. If your doctor felt like you needed something more instant he might have decided on a change. I am not familiar with vistral. Never taken it myself. But klonopin should never just be stopped. Like any benzo you come off it over time. Unless maybe it was only a week you were on it. We would need to know the duration of the klonopin and then maybe someone can answer the question a little bit better.
