"i did 40 day injections and found the diet easy to stick to if you plan your meals, pre weigh and bag about 1 week ahead. i had headaches sometimes as a side effect but tylenol worked. i started at 195 5&#039; tall and weighed 163 after stopping the injections. i waited 6 weeks and now weigh 167 and am beginning a second 23 day round of injections. i am convinced that the weight will stay off. i will continue with each treatment until i get down to 125"
