Sorry I can't remember at the moment who posted on about ALS, because of my leg cramp. I am stunned, I had never heard of this illness, but the symptoms of it totally match Mercury symptoms. Thanks to who ever posted that, especially as other family have suffered with same symptoms and apparently ALS can be inherited. I Know this may not be the answer, but as I said I will get tested to rule it out. Its really worth a look on the internet guys. All my love Tracy
