Excuse me if this is old news,
I live in Canada and found a product at our local pharmacy called Restful Legs.
(Jambes Agitees) No prescription required.
It is unique in that you put two capsules under your tongue and they dissolve within seconds and they are tasteless.
I have personally tried these and they worked for me.
If you can find these or a similar brand I would strongly suggest you try them.
The product is made by Hyland's homeopathic Canada,
Best of luck,
David
