The same is true for Gabapentin. In my personal opinion and experience you want to be able to gauge your RLS on a day to day basis and take meds accordingly. Besides the horrors of withdrawal, these two substances do not give you the opportunity to gauge your RLS. Everyone needs an emergency med such as tramadol, oxycodone, mucuna or ferrous bisglycinate and sometimes that emergency med is taken every night, so be it. But you don't take it until you feel the RLS. That's how you keep your meds to a minimum. And the ferrous bisglycinate should always be the first emergency med you try. If that doesn't work you go from there.
I've heard lots of stories of people throwing away these emergency meds or needing way less when they stopped taking statins or HRT or antidepressants or sugar substitutes or antacids. 1.0mg of melatonin will give me restless BODY for 4 to 5 hours. What other condition in the world is subject to such small swings? By day - no RLS, by night - RLS. What the heck is that all about? It's probably that small drop in available iron or dopamine (or both) that happens at night that causes the symptoms of RLS as has been discussed on here. Why do we want to take 100s and 1000s of milligrams of a drug that doesn't even address either of these two things - iron & dopamine.
Unfortunately, unless you're bed-ridden, RLS is one of those conditions that requires experimentation. Graham has had amazing results with FODMAP diet and many others. Don't just pop pills prescribed by your doctors. Your doctors are the ones who led you down the path of the DA nightmare and now they're leading you down the path of the Lyrica nightmare.
