Query: It's a good book, but...

It is a good program and I'm sure it does work as advertised, however there are some drawbacks. First, some of us can't use it. For instance, as a nursing mother I can't superhydrate until after I'm done nursing, nor can I cut my calories as drastically as advocated without jeapordizing my milk supply (I realize this is a temporary problem). My other major difficulty is that it is a 6 week program, and doesn't really provide much information or helpful advice on what to do when you're not following the program. Frankly I'm more interested in what I weigh a year from now, than what I weigh 6 weeks from now.With those quibbles aside though, it's otherwise an excellent book and program.
