I am just starting on Neurontin 300 mg 3x day. I know that it helps with nerve pain as that is what I'm taking it for. I have Fibromyalgia and was wondering if Neurontin helps with sleep. I am currently taking Ambien CR for sleep and it helps, but my insurance will only cover 14 pills/month. I need something for the other 16 or 17 days a month.
