While it may well be that you can get more relief than you are getting, the first thought that came to mind about the book was wondering if it was by one of those "I'm totally cured and you can be too if you follow my ways!" books. Because... when he claims to have absolutely no cycling, I'm sorry, but he either didn't actually have it or is in remission. Or delusional, which, well, that makes me chuckle with irony.
I won't say that there aren't measures one can employ to smooth the road a bit and improve things in general. But don't get me started on grandstanding gurus. Having all the answers, speaking in absolutes, if someone doesn't reach the top of Everest like their super-fantastic self has, then they just aren't really trying. Because if the
really apply the author's magic formula, it
will work. Any evidence to the contrary is met with this response, which is a ridiculously easy "out". And doesn't prove a thing. The entire super-success guru genre drives me up a wall. And though BP books are barely represented, I just couldn't help but wonder from the "no cycling" thing.
Anyway, sorry about the rant.

Anyhow... if any of that sounds like what you were reading, and it makes you feel worse, you probably want to consider reading something else.
