insomnia
"I've taken Ambien sporadically since 2003. I started using the medication to help me sleep when my husband was deployed.  What a miracle!  I have memories of being four years old and struggling to slow my mind down enough to sleep like a normal person.  I thought that I would always toss and turn and pace the floors of my house for four hours and sleep for two or three for my entire life.  I'm very thankful that my PCM referred me to a psychiatrist to address my sleep issues.  I still rely on sleep aids many nights and alternate between Ambien and Lunesta.  Lunesta seems to be much more mild in my experiences, whereas Ambien just immediately induces sleep."
