I work for a publisher and we publish alot of hokey diet books. I just can't take them seriously. I can't stress good nutrtion enough. I've had a week now, with the proper caloric intake and excercise and I can literally feel myself being lighter. I'm not as heavy as some people(5'5 - aprox. 130) but I have a very small , weak frame that can't support my weight. So when I get above 115 or so, it actually hurts.
If you need folic acid for your sleep problem, then eating foods (limes) high in it are better , in my opinion, than pills. Just don't go on a lime diet.
Good luck!
