The first time I was on gabapentin it took my libido way up. I think that's why we have a second beautiful baby boy lol. This time it took it way down as in no interest what so ever. It effects everyone differently. I'm glad my poor husband is in Korea for the year because I might have to change to a different med. I read somewhere when I was looking at side effects of the different meds used to treat this that it does happen to some people and some people have no side effect of it. It all depends on the person. I hope this helps some.
