Bfree, not sure where you live, but DMSA without a prescription is available in the US at www.kirkmanlabs.com. Very inexpensive. Be sure to start on low doses. Sounds like you are definitely beyond 4 months post amalgam removal so you could do ALA. But start with DMSA FIRST according to the protocol listed on the Andy Cutler frequent dosing chelation web sites.

Best to you!
