This is my last week of 40 injections (1X day) and I've been having a really difficult time. I lost 20 lbs in the first 30 days and hardly anything these last two weeks because I have been ravenous and waking up in the night due to hunger. When I asked the doctor at my weight loss clinic about the possibility of developing immunity after 30 days, she said that the injections should still be working and that I just need to try harder. I can manage the morning without eating and lunch and dinner at 500 calories, but by bedtime I lose control. My next run of hcg will be for 30 days because I think only Jesus can make it 40 days!!!
