[ Women's Health ] Open Question : hcg weightloss question?

I started the hcg diet( using sub lingual drops) at the beginning of june and lost about 22 pounds in the 26 days. I went off of the diet and entered into the maintenance phase. I did the maintenance for a little over a week. I found I was still eating about the same as I was while on the drops. So I decided to go back on the drops thinking that in reality i could have continued the drops to the full 43 day regimen. My question is this. Though I am loosing weight a little slower my second round, if I am still loosing cani continue taking the drops longer than the 43 days since I stopped for a week. does the break of only a week help so that my body didnt build up an immunity? I really have another 10 or 15 pound I want to loose so Id like to keep going a while longer if possible. thanks for your imput. kriket
