When you do bowelcleanse you can also put in a liverflush every 2 weeks.
You will get more toxins out and the bowelcleanse also helps getting the liverflush toxins out.
A very important thing is if you could do a colonic, colema or deep enemas, that will remove the toxins faster.
You could also look in the Ayurvedic bodytype of eating. When you know your bodytype you can see what your body likes or not.
