insomnia
"I began taking Ambien 15 years ago I stopped it while I was pregnant with my first child and then ended up going back on it from lack of sleep for so long. I took it again first time 6 1/2 years before becoming pregnant again and then had to stop it. When my youngest son was a year and a half old I started taking it again because I could not sleep longer than an hour.  When I first started taking Ambien I think the chemical compound was a different because back then I would eat in my sleep, cook meals in my sleep, but then after going off of it and going back on it I believe the formulation changed. I have not had any of those issues for over 13 years. Taking it on empty stomach makes a huge difference."
