Be extremely careful with this medication, it is highly addicting!!! I was prescribed xanax about 10 years ago for anxiety at the same dosage as you are on.
Last year, my brother committed suicice due to a heroin problem and the psychiatrist increased my dose to 5 mg daily.
Now I am in the process of weaning down, and it is no picnic. I have pains and cant sleep at night even though he is tapering me off very slowly. My body feels like it was literally hit by a bus.
Just take the meds for a limited time...Don't let them tell you otherwise!
