I was suffered from severe joint pain that leads to my panic attacks. I have begun to take 1mg Xanax and continued for two months. But it does not provide that much effectiveness for me. I have consulted my physician and tell about my issues and Xanax consumption. Later, he has prescribed Xanax 2mg for me. Within a few days, I have got better results. Now I am so relaxed and calm! Really Xanax is effective.
