I had this from 27 weeks-30 weeks ish....maybe its an Upton thing lol. Mine felt really weird.....the only way i can describe it is like electric going through my legs and i want to thrash it out.Its so annoying though because sometimes it was only a little bit but felt so horrible!! I used to go mad in bed

I agree with supernurse though i was having a glass of tonic water about an hour before bed and it helped as thats good for cramps too,make sure on the ingredients it has something called "quinine" in it though.
I dont seem to get it now though just a little normal leg cramping.
