[EX Q]: My husband and I were not able to attend a birthing class, so the doctor suggested we rent/buy a video. We decided on this one, and although the 'teacher' was a bit corny it was helpful. I especially liked that you could fast forward and skip parts! All in all it was a worthwhile purchase and proved helpful to us both.
[EX A]: Positive

[EX 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.
[EX A]: Positive

[EX Q]: Man, hardly have I watched a movie this long (one hour and 53 minutes) that portrays the leading character in every (I mean, every!!) single scene, every single second of the whole movie!This is a bonus if you are a Diane Lane fan (and who is not? The woman is simply gorgeous, besides being a very good actress!), but otherwise youl will be imersed in a chick flick all along, and a bad one by the way, one that will lead you absolutely nowhere.
