If you are considering detoxing mercury, I wouldnt start it until well after you start methylating properly, and you might not even need to. And you are not going to tolerate dmsa or dmps very well because of their high sulfur content, could wind up worse off pretty easy. Play it safe with the diet at first, then when you’re well down the road add some cysteine/sulfur foods back in and see how it plays out. With a CBS, its easy to become loaded with ammonia if you start supplementing and your not on the diet, and that shit is TOXIC. Im about to put up a methylation symptoms list, ill bet you’ll see alot of your familys health history in it.
