My Dr. is worried that i have been on a narcotic (percotete) for to long due to back pain caused by two bulging disks L4/L5 and S-1/2. I have been now put on Gabapentin. Is this really a better subsitute. I have been taking it for a week now and still have a lot of pain. The narcotic seemed to work better but, I'm not a Dr. I am in the Army and am very active also must drive everyday and make quick life or death desistions on a daily basis. Is this a better alternative
