I was really impressed by the science behind this book, and its insistence on evidence instead of theories. It is very thorough and it was so helpful to hear about all the other women who have suffered from PMS and have been helped by the starch diet and progesterone. It is a shame more doctors, GPs, gynocologists etc. don't seem to know more about this, for example the dangers of taking the Pill with aggravating PMS, or how having a hysterectomy won't cure it, or the dangers of B6. Excellent book.
