On weight loss pills

I've been frantically thinking of some way to write a good, responsible book on weight loss and weight loss pills. I think I found it, so maybe it will be on Amazon soon. I haven't written most of it yet, but I'm working on it when I can. It's not the total book of weight loss, but has a unique angle I think will appeal to people, and provides useful, helpful information. I have to learn to narrow and niche-ify my thinking, to come up with great ideas to write many more books on Amazon using their print on demand service Create Space. I'm also working on books on Kindle.
