From the many times I have went thru wds I know this is the last thing u wanna hear but I have found nothing that helps wih rls I have even tried mirapex which is made for rls and it did not help a lick some ppm say hymena rls helps but it didn't me but u coul try it they sell it at walmart it's OTC and not expensive but I think nothing works because the cause of the rls when in withdrawals is not what causes people who actually have rls so the Mesa don't help but I am no doc and don't know for sure good luck tho I hope something works for you I do agree with the other post I did take the magnesium and I also took 200 mg of potassium and it helped some but did not make it go away
I think it will make it worse. Flexiril relaxes your muscles and when you have rls your muscles are already too relaxed. I have the rls thing bad and i have been on flexiril before and it made it worse for me. Try some magnesium, take it a couple hours before bed up to 1000 mgs. It really does help mine. Good luck to you.
