When I was taken Gabapentin two things happened to me. One was dizziness. The other was THIRST. From being quite phobic to drinking water (I oddly did not like it much), it became my best friend. I had my head under the tap several times a day. It was sooo gooood... LOL.

Of course I peed quite a bit too. Oddly enough I have a relative with diabetes insipidus and she claimed I might have gotten that, but I knew it was a side effect even if it was listed NOWHERE. When I quit the med, that went away after a few weeks.

I have another med now (totally different class), Ritalin, and it makes me run to the bathroom like crazy with urgency. It's not supposed to do that either. Not much coming out though, it's more like my bladder turned pea sized.

There are so many strange side effects that are never listed. Does not mean they don't exist.

Of course my glucose levels were tested (several times), always normal.
