I used Neurontin for over a year, 900mg a day, without side effects.

I also have used Valium (OK, can't remember how to spell Diazapam...uh..Diazopam, no...it is....sorry, having a morphine moment here) -- Those are the two I have used. My RLS went away for 4 years, just came back.

I now take Neurontin every evening -- 300mg. Seems to be working. When it REALLY gets me, I use my Oxycodone. But I have been on Avinza and used Oxycodone for a couple of years, so the Oxycodone does not put me to sleep.

Good luck with it...
