I've been on Gabapentin for fibro for 5+ years (300mg twice a day) for joint and muscle pain. I don't have any negative side-effects and have not had a bad flare in 5 years--a little neck/shoulder blade ache some evenings, but Tylenol takes care of that.

BUT I was diagnosed with Sjogrens in 2006 (extremely dry mouth). Until recently that had resolved itself, but since Covid in 2023, my doctors think the Sjogrens is affecting my eyes, lungs, and kidneys. Apparently what we've been treating as Fibro might be a Sjogrens manifestation!
