Clonopin has a much longer half life than Xanax, which means it stays in your system and gradually "weans" down. I took Xanax for years and years and coudln't get off; I'd taper down to 1/4 pill and still couldn't do it. Then a doctor did a taper schedule for me with Xanax, and started me on Clonopin. I had no problem at all. I assume you are under a doctor's care, right?
Yes it will help. It is a benzodiazepine and lasts longer than Xanax. Someone with more knowledge will hopefully explain this better. It will prevent you from having seizures too. Are you under a doctors care?
