I just came across on Groupon Dr. G's B12 shots for weightless http://www.drgsweightloss.com/
https://www.groupon.com/deals/dr-g-s-weightloss-wellness-3
I know a couple of people that did the B12, even a chiropractor some time ago mentioned to me that she lost weight. It's pretty expensive but Groupon has good deals (i think). I wonder if any of you used or know anyone that did and are there any catches?
