I do think Klonopin is less addictive. I've taken Xanax, too. It works for 4 hours or so, so you will need to take another one sooner. This really only comes into play after consistent long-term use. It's reccommended that doctors don't prescibe Xanax for more than 6 weeks.
I never really felt an addiction with Klonopin or Xanax . Maybe more of a dependence, but I've never thought to myself, "Damn, I've got to get a Klonopin, now." It's just like, "Well, time to take my pills." I think that with antidepressants, too. I've gone off Klonopin after years of use and had no serious withdrawal problem. I just had to taper off correctly. I also had the help of some ADs to help my panic disorder. I will admit that if I had to go off with Klonopin to nothing I would be a total wreck.
