Be careful when you raise the DMSA dosage next time. I am fine with DMSA at 62 mg per dose, but when I raised it to 83 mg per dose it upset my digestive system(diarrhea, cramps, etc.) and I decided to cut it back to 62 mg a dose for the next rounds. I don't know when I will try increasing the DMSA dosage again. Digestive system disturbance is a common side effect of DMSA.
