The yellow urine is due to the huge amount of B vitamins you are taking. Imo taking two B100 pills a day is too much. Some would advise a B25(or even half a B25 especially for someone who is petite) 2 to 4 times a day. If you have dark concentrated urine, then you should be drinking more water. Don't do chelation while doing a parasite cleanse. The parasite cleanse is enough stress on your body. imo you should add raw garlic back to your regimen in even higher doses than you were taking. In addition to killing parasites, it also helps detoxify the body from misc. toxins, and also from mercury. The idea of the wait before chelation is to get the body to rid itself of mercury that is not buried deep in organs. You want this mercury mostly gone first before you use chelation to drag out mercury that is buried deeep in organs(some of which will redistribute. That is why there is a rest period between rounds. To give the body a chance to get rid of at least some of the mercury that redistributed from the previous round. I know the temptation is to doo too much too soon with both parasite cleansing and with chelation, but doing so may cause you to suffer. Taking a slower and more methodical approach is safer, and will probably yield better results.
