Has anyone suffering chronic pain from fibromyalgia or any pain causing condition tried Lyrica?

I've just begun research into the side effects. I've read users reviews and they vary widely. From hair loss to nervousness to many getting pain reduced tremendously and good restful sleep.
If you suffer side effects does the good outweigh the bad?
How long have you been taking Lyrica and what daily dosages?
I'm asking in case it may be something that will help with fibro pain and a better quality of life.
