Just wondering if anyone has tried the B12 and HCG shots. I started them 2 weeks ago and have lost 8 lbs. so far but am also eating about 800 calories a day and walking 4 miles (this is a big increase from my previous 2 mile walks and normal caloric intake.) I think the loss is more from the walking and dieting than the shots but don't know how long I can keep up the 800-900 a day calorie restriction. They also give you Adipex which I have taken a few, they are an appetite suppressant and really work good. Your thoughts?
