"i have only been taking ambien for 3 months or so.  i too have insomnia.  i can get to sleep but wake up and can&#039;t get back to sleep.  my experience with ambien has been crazy.  i have had a phone conversation and made plans to go to lunch with a friend, and when she called the next day to see if we were still on, i had no memory of our conversation.  i have cooked scrambled egg/cheese breakfast at 11pm and put it away for breakfast the next day.  last night, however, was the scariest.  i vaguely remember sweeping up hair, so i looked in the garbage this morning and was relieved to not find any hair. i passed it off as a dream.  then i took a good look in the mirror, my bangs on the left side are now only 2&quot; long.  how embarrassing!"
