I know exactly how you feel Sasha. I also get restless legs syndrome(R.L.S). Although I've had it even before pregnancy and my mother also gets it aswel. I heard that it is caused by caffeine and smoking, but since being pregnant i don't do either(although i do have a cup of tea occasionally). So I'm not sure why i still get it.

The only way i get any sleep is also by using the pillow between my legs. I find that the coldness of the pillow eases the, what i call, "ants inside your legs feeling".

Hope you get some relief, if you find cures let me know
