IV DMPS and FDC together?

I'm new to chelation so sorry if this question has been asked before. I googled but I couldn't find the answer. I'm currently having IV DMPS + glutathione once a week and I'm thinking of starting the frequent dose chelation along with it. Is it a good idea to do both at the same time? My doctor says I can add ALA if I want to but I'm a bit hesitant since Cutler says it's better to start with DMSA first and then do both of them together. Anyone who skipped DMSA and went straight with ALA? I know that a lot of people who do FDC don't agree with IVs since they're two completely different things but I'm just wondering if there's anyone who did both. Another thing is the DMPS dosage, mine is 2 ml when I have my IV, is it high or low? Tweet
