has anyone taken Neurontin first then got off & started they Lyrica?? i was put back on Neurontin after a few years of being off of it, and WOW in 3 months i have gaines probably 12 pounds and i sure didnt need any help gaining weight! i was on 300 Mg a day & decided to get off of it 3 weeks ago, i probably have lost half of the weight i had gained on it. and the 300 Mg was barely touching the pain, so im afraid doc will just up the neurontin for better pain relief, but i cant gain all that weight, does Lyrica make u gain weight?? she decided to put me on Neurontin cause of the cost.
