"i&#039;ve had severe panic/anxiety disorder for 15  years. was prescribed xanax 1mg 3xday for 15  yrs. it worked for panic attacks, but not for constant anxiety. psychiatrist prescribed klonopin 3 months ago, 1mg 2 x day. it has been the best medicine i&#039;ve taken for the daily anxiety, but does not stop panic attacks. talked to him about increasing to 3 x day and he refused to listen! i&#039;m stuck with 2xday. it is the best medicine i&#039;ve taken because lasts about 6-7 hours. i&#039;ve been participating in life again, but anxiety is still ever-present. i wouldn&#039;t have to take xanax for panic attacks if my dosage were increased to 3 x day, but he prefers to prescribe 15 xanax/month on top of klonopin rather than stick with klonopin alone. overall great medicine."
