Getting more calcium may help too. I have terrible restless leg syndrome (usually about 8:00 every night) and drinking lots of water, exercise and calcium lends to help. Also stretch a bunch. I get down on the floor and do some v-sits and hamstring stretches before I got to bed. Hope this helps!
I was having this problem in early December, and my OB prescribed me extra calcium supplements... and they've done wonders! Maybe ask your Doc (or whomever you see) when you go in next, or call, if you don't have an appointment soon. I hope they stop!
I got a wicked one the other morning, and it was sore for a few days! I'm trying to be careful when I first wake up not to stretch my legs all the way out--that's what seemed to start it last time. This was in one of the e-mails I got this week:
Calcium and magnesium will certainly help and if you think its potassium there are LOTS of other fruits and veggies that have as much or more potassium than a banana (avocados are the one I remember but I actually googled "foods high in potassium" once and was surprised at the list: bananas are pretty low down) I'm allergic to bananas and coconut (also high in potassium) so I was concerned about how to prevent leg cramping as well and info on other foods to eat helped a ton!
