In 2010 I have been on 21 day hcg injections for 4 rounds already. My fourth time on it was totally unsuccessful because I was so hungry... consequently I cheated quite a bit and lost only a few pounds. Since stopping the injections 1 month ago, I still have constant hunger!!! Any suggestions on how long I have to wait before starting injections again? I have 25 pounds to lose now....that number is quickly increasing because I am so hungry!
