"i have taken xanax for about 25 years but only as needed.  there are many years i never took any &amp; there are years i took it for a few weeks to help with my anxiety, stress of having a child with a deadly disease &amp; the depression that ensues.  i usually take the .5mg &amp; cut it in half and only use it 1-2 times a day, occasionally 3 halves a day.  it soothes me &amp; helps my constantly chattering, negative mind take a break.  i have tried ssris &amp; have symptoms of being allergic to them, so can&#039;t take them, ie muscle twitching, rash &amp; itching.  so, xanax is my only recourse.  i know it an be addictive so am very careful to take it only as needed, short courses, &amp; usually about half the amount the dr. prescribes.  it has helped me greatly."
