For a tiny book, this packs a wallop of information. I work in the medical field and have been searching for answers to my questions about varicose and spider veins for a long time. I was pretty surprised to learn that the doctors and nurses I work with were as ignorant as I was! The next step was the medical library. I searched for a book--and all I came up with were medical texts the size of phone books and filled with medical jargon. Being in the medical field, I understand the jargon but I really didn't want to wade through it to get the information I needed. Then I found Get Rid of the Blues on the web. What I like most about it is that the author did tons of research (from those boring books I didn't want to read!) and boiled it down to a "cut-to-the-chase" primer. Thank you, Mary Johnson, for writing this book. I can't begin to tell you what a difference it's made for me.
