I may be a complete very small minority on this but thought I would share my experience with taking gabapentin just in case it affects anyone else similarly - It was a few years ago and not related to knee issues but I was prescribed it to actually try to help with Migraines.
After I started taking it, I became increasingly angry and easily irritable, which is uncharacteristic of me. It was pretty much every day and I would consider it almost rage inducing. I would wake up the next day and couldn't understand why I was so mad about the smallest things.
After about a month of this, I quit taking them and got back to normal. I researched it and it appears that it may cause this effect in some people.
