I am a VA patient, have been taken off Opiates, 10mg Methadone tid and Norco 10mg/325 tid. They have put me on Gabapentin for pain. I have ruptured dics L4,L5,S1. Gabapentin doesn t seem to be working yet VA continues to prescribe it saying that it takes time! Been on it for 6 months, how much time does it take. VA Doc will not commit to that answer! Does it also cause constipation? Seems there is a directive to take ALL VA chronic pain patients off Opiates. Wondering if we are being test subjects for Big Pharmacy companies for their Physic drugs? Sorry, I am a Disabled VET living on SS at $700.00 a month,need every penny to survive, $15.00 is more than I can afford! Thanks anyway. Back injury and lack of education has caused me to not work very much!
