Any suggestions on which is stronger klonopin or xanax (alprazolam)?

Neither: When given in equivalent doses, they work essentially the same. However, xanax (alprazolam) gets in quickly but is very short-acting, and has higher abuse potential. Klonopin (clonazepam takes several hours to peak, but sticks around for a long time, and has somewhat lower abuse potential. For gad, antidepressants work well and don't have dependency risks, psychotherapy also works with no risks.
