Blimey! what are we to do I dont know? I am going to have a good look at dietary potassium tomorrow - how much can I get from bananas dried fruit etc I do agree with those who said that mafnedium has helped, but transdermal magnesium (spray) rather than oral. I wonder if there is transdermal potassium? For those using the salt - doesnt the sodium cause a problem with blood pressure?
