"i started taking ambien about 3 years ago.  when i first took it i did make the random phone calls and would eat in my sleep but it worked.  i only took it when i absolutely needed to.  i stopped for about a year then the insomnia started again and i took it again and the side effects weren&#039;t there.  i still take it every once in a while when i really need it (maybe once a month) and the side effects are still gone. just sleep and i don&#039;t feel groggy in the morning."
