DH has been plagued with this for years . Full jerking limbs and sleep deprived. Meds work for a while and then useless.
It may well be too soon to say but having a bath each night with Epsom Salt in has been wondrous . Hot as you can stand and stay for 20 minutes . Soothes muscles and good for skin also I have read . No restless legs since .
Hope this tip helps .
