I once asked somebody in the brain injury room how gabapentin works and they said don't worry about how it works. I thought that that was a naive and dangerous answer so I looked it up and now I know how it works. However I can't for the life of me find out why it makes you hungry. That is extremely weak on the makers side to just put side effects without a reason why they think they occur. That is my opinion anyway for what it's worth lol. if anyone smarter than me which isn't hard knows the answer I would love to know
