I loved this book! The writing was so sharp and funny, and the story is heartwarming and hilarious, without being overly sentimental.Susan Edsall does suggest you go off coffee slowly before you start the plan. This would minimize headaches during detox. I couldn't wait to get started so, of course, did it all at once and had the most horrible awful headache for 4 straight days. I finally broke down and had a 1/2 cup coffee one day instead of taking aspirin and that did the trick...for the moment.You feel as if you've known the author and her family all your life after reading this book, and you really care about them.
