It would make sense that the amount of mercury exposure a person has had over their life time would be a big variable in determining how much sickness they get from the rounds / dose. Since I haven't had vaccinations in a long time and never had amalgams it makes sense that I would be able to go the longer rounds and at higher doses.

If I get up to 100mg ALA doses with 50mg DMSA for a week and don't feel any ill side effects I'll most likely discontinue this as there isn't any significant amount of mercury in my system- which hopefully is the case.
