Chelating again - can we start with ALA?

[Guest guest]

When my son was 6 he began displaying facial and vocal tics suddenly. I chelated

him for 10 rounds (3 days on, 11 days off) using first oral DMSA, then a

combination of ALA/DMSA. The tics went away gradually but came back with a

vengeance a year later following a dental appointment (stainless steel crown). I

am starting chelation again following AC protocol, but am wondering if I have to

start with DMSA again or jump right into the ALA. He has not had any

vaccinations and has no amalgams so I'm thinking he shouldn't have too much

mercury floating around in his blood? Any thoughts?
