I Have Severe Sleep Disorder..so Doctors Told Me To Try

I have severe sleep disorder..so doctors told me to try alprazolam 0.25 whenever necessary...once before going to bed at night...After 1 month I am getting no sleep and above that alprazolam is proving to be turning into an addiction...Sometimes I find it hard to concentrate without that dose...Should I quit right now...by the way my age is 24
