Charley Horses

I am almost 24 weeks pregnant, and have been experiencing charley horses during sleep. Sometimes I have none, other times I experience 4 in one night. I spoke to my doctor about it today and she seemed to think it was normal. She suggested I start taking magnesium.

Anyone else experience this? Anyone else been told to take magnesium?

**It should be noted she told me not to eat bananas due to an issue with constipation. She said the magnesium would help with this as well.
