Try to finish the round if you can. If you can't, then stop the round early, wait a few days, then next round use 50 mg DMSA, 25 mg ALA. If you complete the round, and it wasn't so uncomfortable, then you should use the same dosage next round. If it was uncomfortable, then do 50 mg DMSA and 25 mg ALA bext time.

One other thing. To minimize side effects after the round, it is a good idea to take DMSA only the last 2 or 3 doses.
