Congrats on your weight loss! I found this thread and had to post. I recently found the HCG drops that you put under your tongue and I ended up buying some. I started today.. The first 3 days you take the drops and eat like a pig. You're supposed to eat everything in site. After those 3 days you eat the 500 calories for the next 18 days. I want to try and go for the 40 day challenge with the HCG, but I think I can only do it for 21 days. Right now I am 167lbs and hope to lose about 30-40lbs. I am hoping that once I lose this I can start to eat healthier and maintain my weight. I'll keep everybody posted to let you know how it goes. Has anybody else tried the HCG drops?
