does anyone know which is stronger and/or better for anxiety/panic-- xanax or clonopin? the only thing i have really noticed is clonopin lasts longer and is more sedating. i been on xanax for years,but at times when i run out of xanax,i take clonopin until i get my xanax refilled.i totally hate the fear of running out, whether it be u'r own fault or not. you know--thanks for any comments
