I am 35 weeks at the moment and have had restless legs for a few months now. Sometimes the only way I can sleep at night is if I stay up really late and get so tired I just zonk out. Walking or doing something a little active helps a lot-and a hot shower works wonders. I didn't have this problem with my first baby. My OB says it might be triggered by micronutrient deficiency in some people, but since I"m taking prenatal vitamins, that's probably not it.
