Good luck. My family doc likes the drug, but took me off immediately when I explained my symptoms. He won't put me back on because of that. Yes, twitching, worm-like movements of the tongue (sounds nice, doesn't it?)...not good.
As I said, I took it at bedtime for YEARS. I'm still just fine. So don't worry unnecessarily. I'm sure it's an individual thing, but in my case once I went off it I had not symptoms whatsoever.
Good luck with your recovery!
