I am taking both ALA and DMSA, 50 mg of each, in rounds that are 3 days(3 days, two nights). The last two or three doses each round I take only DMSA. The ALA seems to be what brings on the muscle ache, as I don't seem to get them during the last few doses that are DMSA only. I think I will stick with this scheme unless the symptoms start getting much worse or much less. This is my third round at these doses.
