I was taking xanax .25 to .50 as needed for a few months. My Dr switched me to klonopin .25 twice a day. I have tried for a few days but am more anxious than i was before. Can i just switch back to the xanax? Is .25 three times a day a dangerous dosage of xanax? I am petrified of meds!!! (after a terrible experience with lexapro)
