insomnia
"Having dealt with death of husband, shifts in job responsibilites, grad school and child, I was in the midst of massive depression and anxiety.  I was on Ambien 10 mg for 8 months, which helped, I slept but the fact of addiction was ever present.  I was switched to gabapentin by my neurologist for migraines, and taken off the Ambien.  I thought at first it was useless, I was wired and wide awake, but by the third to fourth day, I noticed I was dreaming again, which I had rarely done in 9 months.  I feel much more rested, where as I had been taking naps any day I could, due to insomnia even on Ambien, and hardly need to now.  I do feel somewhat groggy, but I only take it at night, and it is 600 mg. dose."
