The pills can not increase or "WAKE UP" HCG. You can only get increased ammounts if you become impregnanted or you take "REAL HCG" or homeopathic drops. However pills without hcg can not help wake up anything. YOu are losing weight but you are doing so unhealthfully by taking these pills. You don't believe me, go ask a doctor.
You can take pills all day long that contain no hcg and you will still lose the weight, so yes you are seeing results but you are also not seeing the damage you are causing by such a low diet without the proper medication. And yes your hunger will eventually subside because your inner stomach will shrink over time thus making it easier to eat in small ammounts. You have trained your body to eat less and thus in time the hunger subsides. This does not mean however that some pill is gonna make you magically produce hcg unless you are going to a doctor in real and getting an approved drug that does such.
