First of all, buyers should know that "Sleep for Success" is a brand apparently owned by Dr. Maas. The book describes a "method" of improving sleep that doesn't require anything, but it does point out various items to buy.
Second of all, this "method" isn't really that impressive as a method. In fact, the author only spends one single chapter on it. The first few chapters are about why you should be concerned about your sleep, which if you're considering this book you probably already know much of it. More interestingly, at least some of what is claimed about how sleep works and the effects seem to contradict descriptions by other neural-scientists and sleep specialists; not in any major way though. Following this pitch the author spends one chapter explaining what amounts to no more than, "Get to bed earlier." That's it...the major method. Go to bed 15 minutes earlier until you're not tired anymore.
Of course, the author spends a great deal of time explaining that people don't even know that their tired most of the time, so how do you know? You buy tools of course. Maybe a good idea, but one should be aware that this is the main pitch of the book.
The other secret, the great way to stop using the snooze button? Buy one of those clocks that runs away screaming. If you've not already seen it on thinkgeek or maybe here on amazon then this might be a new idea to you...I found it very anti-climactic. It's just a clock with wheels that starts running off in random directions while going off so you have to get up and hunt it down. Idea being of course that once you've gotten up you won't just go back to bed, or won't just sleep through the clock (especially once it's crawled under something), which anyone that actually does have sleep problems knows is complete bunk.
Another bit of advice that seems off the deep end is the author suggest reading for enjoyment before sleeping. I suppose for some this might work but as one who's gotten so involved in a book that they're still up at 5AM saying, "Just one more chapter," I'm not buying it. What might have seemed more reasonable would be, "Read something that bores the HELL out of you," but the author suggests NOT reading something for work.
After the single chapter that describes this new method for sleep success, the author talks about some other issues that may or may not mean anything to you, like children and teens...I'm not a parent so about 1/2 the book is a total waste to me. There are some common sense statements like don't drink caffeine in the later part of the day, don't get drunk before trying to sleep...etc... I suppose there's enough folk medicine about taking that sleeper shot that needs to be put to rest, but really most of the book is nothing but common sense.
Of course, most people don't have common sense so if, "Get to bed early," and, "Don't drink coffee before bed," seem like new ideas to you then this book is probably exactly what you need.
