I started this round with 75 mg ALA plus 50 mg DMSA. After the first dose I felt strong muscle ache, but after the second dose my muscle ache is much milder. I am glad I didn't try to use 100 mg of ALA this round. If this round goes well, then I may stay at this level for a few rounds before going to 100 mg ALA + 50 mg DMSA each dose.
I am wondering about which supplements might interfere with chelation. There are two that I immediately suspect, which are zinc and selenium. I read about one study on rats in which the presennce of sodium selenite caused less mercury to be excreted from the kidneys while doing DMSA chelation.
I read that zinc reduces the effectiveness of DMPS chelation, and also read that zinc is chelated to at least some degree by DMSA, so having extra zinc in the bloodstream during chelation might decrease the amount of mercury and other toxic metals excreted. Since DMSA does cause increased excretion of zinc, it is probably a good idea to take zinc supplements between rounds, but not during rounds.
