HCG Diet help

Hi,

I am 25 and doing the HCG diet.  I am 5'6" and 161.2 lbs (from 167).  So I've lost 6lbs but I am constantly starving.  This is my 3rd time doing HCG and the first time wasn't hungry at at all, 2nd time I don't really remember.  I followed the protocol to the T and can't do it anymore.  I finally gave in today and ate something off the menu... I sleep 8 hrs, am not using ANYthing on my skin and even bought a shower filter.  I tried different variations of meals and am drinking plenty of water.  The nutritionist at the place I got the (injectable) HCG they can't really help.  Nothing is different from the first time so I have no idea whats wrong!  I didn't realize it but I started the protocol during my PMS week, even so that happened the 1st time and I wasn't hungry.  I don't understand what I am doing wrong.  I am taking L-Glutamine and Chromium p.

Thanks
