I take Lasix for swelling in my feet and legs, and I have been
having some horrid leg cramps lately.
Definately take potassium in your vitamins, or in a
seperate supplement. As Patty said, Bananas and green
leafy veggies are excellent sources. Oranges are a
good place too!
Have you ever heard of quinine water? My mom's doctor
told her to drink it, and it helped her cramps. I think it's
alot like tonic water.
Also, (this post is starting to sound like a infomerical

)
Make sure you are drinking enough fluids. Dehydration
can cause cramps too.
If you get them while you sleep, another thing that has helped me
is making sure my sheets are not waded up so my feet don't
get wraped up and in a bind.
I had gotten an info sheet from my medical doctor not
long ago on cramps, don't think I'm really this smart. :p
I hope some of this helps!
God bless!
