Query: Really good but one thing i didn't like.

This book is great.Great. tips, great advice, and most importantly, it does what it says on the tin.Cure you headache in 1-2-3.There is one thing i didn't like about this book though.It reminds me more of a T.V ad or a product, but not a book.I don't see how you could write a whole book about it, when it's only suposed to be 1-2-3.Other than that this book has realy scientific knowledge and David Buchholz really knows his stuff.He gives as it is advice about headaches and says that they are all a form of migrane.How strange!This book is generlay great, but with that one little problem of reminding me of a T.V ad or a product other than a book.If i were you i would buy this book, and solve all you problems.Remember, it's a easy as 1-2-3!Sam Worrall rating:4 stars.
