my ex is a Vicodin addict, and now i found 4 pills in his truck, looked them up on here, and they came up as gabapentin. since he does not have epilepsy, I don't know why he would have these. it did say in the description NOT to use with Vicodin Which I know he uses daily. Is there an effect from using the 2 together? I am confused. If any one knows, fill me in. We have kids together, so i am already worried knowing about the constant Vicodin habit, but now am starting to suspect there is even more pills apparently.
