Was it the same physician who has had you on klonopin all these years? If so, interesting that he decided to stop all at once?? Something obviously influenced this decision but he should also realize you need to be weaned off rather than just stopped? He's either run into an issue with someone over this med. or something else is up for him to change his stance so abruptly with no explanation? And no weaning schedule? Wishing you the best.
