Hi I have just been diagnosed with fibromyalgia. I am taking Gabapentin 600 mg twice a day. They seem to work for a about two hours and then my pain and stiffness return. Should I talk to my doctor about increasing my dosage or is there a better medication to try? He gave me Gabapentin instead of Lyrica due to the cost. He said it was the same medication, the only difference is Lyrica is time released. Could I possibly take a pain medication with this? maybe that would help. The Gabapentin sometimes gives me a terrible headache. Thank you.
