devin319, it sounds like you might also be lacking magnesium in your body. Magnesium deficiency has the same symptoms. Many of us suffer from this because we eat too much processed foods, fast foods, pastas, bread, etc... The magnesium is refined right out of them. Take a magnesium supplement, about 600mg a day, divided into 2 or 3 doses. Take on an empty stomach, and for sure never eat it with a high fat meal, or it won't get absorbed. Magnesium is nature's relaxant and is well known for stopping palps, angina, insomnia. It is used in ER's to treat people with asthma attacks. It relaxes and opens up the airways. Read the book, "The Miracle of Magnesium". It's a real eye-opener.
