Since I have been implementing more IF into my life lately I have been doing a lot of reading about it and have found some great stuff on Robb Wolfe's website. I thought that it might be helpful to those of you considering trying it yourself.
Make sure to read the information FIRST before attempting IF, since Robb clearly discusses the fact that there is an order of operation that must occur before implementing this kind of thing into your lifestyle...
