panic attack and insominia, so dr put me on xanax 0.5 mg 2 times a day and take 2 at night for sleep, havent taken much during the day only if really needed, but afraid of taking it at night for fear of xanax being additictive..and after going thru detox dont want to be doing that again with xanax, but they say short term should be fine and i really NEED to SLEEP, anyone out there have some input on this... has anyone else gone thru this too? thank you
