Ambien
"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'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't feel groggy in the morning."
