I sympathise!!!!! I started get restless legs around the time of my 20 week scan and they got worse and worse, lasting for hours in the evening - my OH started going to sleep in our spare room as I kept kicking him by accident into the wee hours! There was no chance of me sleeping through it or ignoring it so I looked up stuff on the internet.
It drove me nuts, but since I started taking iron (100mg) a day (my iron was 10.6) and eating more magnesium (peanut butter!) they've eased alot.
good luck girls, hope you don't suffer to much with them!
