Neurontin etc. (Gabapentin) When i was first started on Neurontin, it was such a small does it didnt really do much good, but then I began seeing a new FM doc and they put me on the max dose of the med. I take one 600mg tab at 8 AM & 12 Noon and 4 tabs at bedtime. For me, after they upped my dosage it became my miracle drug. I stopped having migraines that were sending me to the ER once or twice a week and it helped with the sleep deprivation. Again, it's my MIRACLE drug!!
