question:
This book was a wellspring of information for me as a newly diagnosed type 2 diabetic. Getting off the cycle of being told to eat complex carbs, seeing my blood glucose spike from doing just what I was told, and getting medications increased again and again, I read what Dr. Bernstein said with interest. After trying his recommendations I can say with no reservations that this book may have saved my life! I highly recommend it to anyone who has pre-diabetes or diabetes and hope that the general medical community opens their eyes. After only one day of this diet my blood glucose readings were close to normal, and continue to stay there, with less medication. My energy levels are high and I have felt better than I have in a long long time. Kudos to you Dr. Bernstein, for daring to say the truth! I recommend both his books and also Dr. Atkins Diabetes Revolution to anyone who wants to learn about diabetes and diet.
answer:
Positive


question:
It does an excellent job on mildewed wood such as decks and deck furniture without using chemical mode which is the only weak link in an otherwise strong chain. Unfortunately, the only effective chemical solution is chlorine which acts more or less on its own but cannot be used with this machine. Safe cleaners, such as Simple Green are no more effective than when used without them. Other than that, it's a great product.
answer:
Positive


question:
This seems like awfully shoddy science fiction to me. The old complaint about thin characterization isn't even the worst of it, nor are the crazy anachronisms [rampant cigar smoking, newspapers and casual misogyny]. But so much of this plot develops in the form of uninteresting local political maneuvers between slightly AynRandized heroes and buffooning villians, with no sense of place or grandeur whatsoever.The timeline of the novel is suddenly too breif after introducing the vast concept of a 40,000 year swing through history, and neither the future society Asimov has envisioned nor the apparant brilliance of the plan at the heart of this series are ever portrayed convincingly. Whatever powerful effect this book may have had in its day, it is bereft of it now.
answer:

Negative
