It appears you try something and then switch to something else. I used to do that and figured nothing worked. Colloidal Silver for instance. I tried that 5 years ago and felt nothing happened. Then my doctor, 2 years ago, suggested I take it and use a different brand. It did make a difference longer term and using different doses. I have been taking it for a year and a half most of the time. With other things that I have taken, samento for instance for 6 months, then Iodine for 5 months, I have made a 50% improvement in my health. Also chelating mercury. But it is a long process. Out of all the things I have tried, Iodine seems to be the best so far, but I did not feel that way when I first tried it, and probably would have quit it if I hadn't read all the informative posts in this forum.
