I have been taking xanax for years now for my anxiety disorder/panic attacks. I went to the doctor today and he wrote my prescriptions. I filled them and came home and noticed that it was ativan not xanax. I took one and it didnt make me sleepy. I like that. So the question is, is the ativan stronger than the zanax? will ativan work better than xanax? I know nothing about ativan eccet that it is used for anxiety.
