i think the problem though Vic, this that it's a bit of a loaded question. It's in the general sleep section and you have asked for those that have read the book to list what they have and haven't used. Many have replied they have read the book, but used little to none of the advice and listed what and why. So in people's defence they have stuck to the OP.
Maybe this thread would be better in the CIO section with a clear direction that only Tizzy supporters can reply?
