hi sunshine p. your very wise to stay at your current dose , don't make the mistake I made by increasing your dose too quick , I 'm still paying for it , it has been almost a month now since my crash and am feeling a little better but still feel pretty bad most of the time , if I start chelation again I will be using a 10 mg dose of dmsa only , I think that when I added the ala it was just too much for my system to handle and was only at 25 mg of each , I know that some people in this forum don't think that dmsa by itself will remove brain mercury but I have read many articles that dispute that , and say that it does , if dmps removes brain mercury why shouldn't dmsa
