I'm not really anti Bill Phillips like some other reviewers and I don't know his history. I bought this book, followed the technique to a key and felt worse after. I have a feeling it was the supplements because I never had such headaches just from working out, and I've been working out for years. Somethings I did find annoying like the "late night infomercial" tone through most of the book and each page had the e-commerce website on it six times. I will give credit to Mr. Phillips ability to motivate people but I'm not convinced Anthony Robbins won't do a better job for you.
