I did not feel like it helped but it made me sleepy. I began taking all three doses at night to help me sleep. I felt very rested during the day and able to cope with my anxiety. After a few weeks I tritated down until I was off the medication. I see my doctor this week and I want to discuss taking zanax as an sleep aid. Is it all right to take 3mg nightly or 3mg at a time? What is the common doseage of Zanax for women who are 60 and older?
