insomnia
"I took my first Ambien last night. I laid in bed for almost an hour before I took it, then after taking the Ambien I would say I fell asleep within 15 minutes. I did wake up twice during the night but went right back to sleep and woke up at 6:15 this morning with a clear head and refreshed. At this point, I think Ambien rocks. I have always had trouble shutting down my mind and falling asleep. I have tried numerous prescriptions and over the counter medications with unsatisfactory results."
