My belief that the best alternative, completely natural solution is probiotics. Joe, it sounds like your digestive system may be infected with harmful pathogenic bacteria that are producing toxins that your organs cannot cope and therefore under severe stress.
Of course, I must declare that I am not a healthcare practioner nor medically trained but has lots of information on digestive disorders.
You need good probiotics not just 'freeze dried' powder or tablets. The 100% live multi-strained lactic bacteria in quantity and quality that can get to work on the entire digestive system (both small n large - bowel intestines). That will clean and ease the effect on yor other organs. However, you should check with your competent healthcare advisor or doctor.
