It's an anticonvulsant or nerve pain med. I took it to get off heroin as it helps with the Jimmy legs and helps with nerve pain or discomfort. However, whenever I would come off heroin I would get horny. It's something most opiate addicts experience when they withdrawal and even after your withdrawal stage you are so much more alert. All of your senses heightened as they've been taken when you sold yourself to not feel pain..or anything for that matter. So since I always used gabapentin aka neurontins whenever I would attempt to get off h the suboxone route I would take neurontins frequently in my5 day taper and I just remember how horny I would get while withdrawling and I'm pretty damn sure the neurontins only enhanced it.
To this day I am almost 2 yrs clean off heroin, as I'm sad to say I went the methadone route this last time, and it has been the only thing to keep me off heroin.
I am getting off topic so let me just say it now. Even being on methadone, I can't take neurontins without getting horny to a state of discomfort unless I have a few hours to have multiple orgasms. And unfortunately to me, I'm stuck with the least sex driven mate I have had to date.
