I was on it for neuropathy at a pretty high dose, corgi (2300 mgs). My condition improved and I tapered off it. Yeah, I had some w/ds but they were not as bad as benzos.
If it helps your fibro, if it were me, I'd stay on it. If/when you do want to taper it off, just be aware that it is likely to produce w/ds.
Best,
