... have other insurance, I really cannot afford to take this as they have raised the price so high ( even with insurance ). Can the Lyrica be replaced with Gabapentin ? Also, what are the side effects when you wean off the Lyrica ? Should I ask for the Gabapentin and start on it before weaning off Lyrica ? I have taken both pills before due to a concussion, but not sure of side effects. I have had fibromylgia for 30 years.
