[Q]: 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.
[A]: Positive

[Q]: I can't pick up my own guitar without trying to play some of the lines Duke puts together on these numbers! He really smokes on "Easin' In". Unlike what some others may say, I think his swing chops are awreet and that the major problem here is that Herb Ellis is a little stale and staccato, but that's only compared with the Herb of yesteryear. This album is a fine excursion into this genre of jazz/blues and will be appreciated by more than just a purist jazz or blues oriented audience. Buy it and enjoy!
