Hi CMT,
Thanks for the question, and a very good one, I have sent an email to my doctor to get a more detailed repsonse as to why, he may have told me but it never sank in, I was that happy with the way things are going so may hav enot listend .
As soon as I get a response, knowing him it will be within the next 24/36 hours maximum then I will post the repsonse.
