Hatlady, do try your Ambien. Just do make sure you have a block of eight hours sleep and when you wake, you won't be groggy. I used Ambien a couple years ago, I believe when it was first being advertised. I had a really bad block of insomnia (I'd stayed up straight three nights in a row) and the doc had me try these.
They worked very well in breaking the cycle of insomnia. The reason I did not stay on them, and I could be wrong, but I understand that they're only to be used for a little while, is that I stopped dreaming. Dreams I believe are very important to one's health.
