I think you should control your pain by reducing your dose instead of taking tylenol, which causes liver damage. There is only so much muck your white blood cells can hold before they become engorged. When you get a headache, it means you have released more toxins than your immune system is capable of cleaning up and it is circulating through your system looking for a way out or a new place to lodge. You cannot rush the parasite cleansing process. It will make you too sick to continue. And then you will end up at the emergency room. And if you tell the doctors what you have been doing, they will want to know which herbs you are taking, so they can report this to the CDC. It will tell the FDA those herbs are dangerous, and they will ban them and nobody can use them any more because you tried to cleanse too fast.
