"i was 61 before experiencing anxiety.  it happened when i quit smoking (2 packs a day).  if i smoked, the anxiety stopped.  i wanted to quit smoking very badly.  i quit 5 months ago. i take 1/2 dose of alprazolam as needed, usually twice a day.  no side effects.  i could not have quit smoking without it.  hopefully, i can wean off the alprazolam gradually over time."
