"i have used xanax for the past 15 years for moderate to severe panic and or anxiety attacks. were it not for this drug, i am not sure what i would have done. it was and still is a god send. i only use it as needed as opposed to daily use. two downsides are that it makes me drowsy and if i drink alcohol when i have taken it, i get very testy.  don&#039;t drink and drive and don&#039;t drive while on xanax."
