I am also a 20 year old and feel like an old man... I think Liver Flushing is important to keep going, but you should also read through Andreas Moritz forum and see what he thinks about how to get well. He seems to have the most insight into how the body works than anyone else i've read about, and its all without any products. He says most ailments can be fixed by colon, liver, and kidney cleanses, along with improved diet/lifestyle and addressing any emotional issues. Candida, parasites, and the need for supplements will vanish on their own if you do this.
