I have CBS C699T (+/-) and CBS A360A (+/-) and I'm on the Cutler protocol. This means that I'm taking DMSA and ALA to get rid of some mercury burden. My plan was to address methylation when I'm done with the Cutler protocol. The problem is that I discovered that I have CBS (+/-) (which is worsened by the fact that I have BHMT (+/+)). According to Heartfixer: "Sulfate/sulfite overload due to the CBS up regulation is likely playing a key role in your sensitivity to heavy metals and/or your inability to clear them. [...] We can hold sulfur containing agents until your sulfate burden has come under control." I'm 3 months in on the Cutler protocol and I feel significantly better in some areas of my health. I've cut out all sulfur foods. My main diet now consists of fruits, vegetables and vegetarian alternatives. Do you think that DMSA and ALA form a problem?
