My cousin gives me a discount on my .3% THC CBD oil at $80 an ounce that last about a week or so for me. I'd say 5% is a lot!
By the time I used CBD oil I was so miserable with RLS that I would have made any sacrifice to get relief.
I pray u find a cheaper solution. I tried gabapentin, Requip, pamelor (so), Quinine, Tramadol. Some worked for a while, but, for me, suddenly, nothing worked.
Having the CBD oil, full spectrum, .3% stop my RLS has been a miracle.
I suppose it could stop working, but after 3-4 months, it is still working tho I have to take an extra dose or two some nights.
