Acupuncture for chronic migraines: Has anyone found lasting relief?

I've tried numerous medications and lifestyle changes for my chronic migraines, but nothing seems to break the cycle. I'm exploring alternative therapies and have heard mixed reviews about acupuncture. Before I commit, I'd really appreciate hearing from anyone in this community who has genuinely found significant, long-term relief from frequent migraines through acupuncture. Is it truly effective?
