"simple, i started taking ambien in 2001 when it was prescribed for me by my orthopedic md for a swollen knee so i could sleep, then i found out it was not habit forming, other than psychological.  i am a professor and i have trouble shutting down my mind at night.  i have used it daily since that time, never have needed more than 5-10mg, never sleep walk, do my best work in the morning at my office before classes, have gone a few days when i have run out and am not somewhere i can refill.  doesn&#039;t worry me, i just accept i am not going to sleep well and i don&#039;t, but i sleep some.  i don&#039;t get anxious about it.  i am now 71, still teaching full time, no sign of weak bones.  why on earth would i want to stop taking ambien?"
