Yes, Sosick I am worried about the DMSA with his gastointestinal issues. I had read that DMSA has more gastrointestinal side effects than DMPS and that transdermal DMPS has the least gastro side effects. So I thought maybe I should go to a DAN doctor to at least see if I can start off with transdermal DMPS until the gastro problems are more under control. I don't know. It is so confusing. I did find a doctor nearby who from his website appears to be very good. He is a DAN doctor (and a yogi). He promotes things like Epsom salt baths and has plenty of great testimonials on his site. Maybe I will do the DMSA/ALA combo (low dose) with my oldest who has no gastro issues (only attention) and take my youngest to that doctor. I will keep reading. I know what you mean though about being wary of doctors. I saw a number of them who took me lower and lower at each visit (more antibiotics! - the answer to everything). But I think there are a few good ones out there. They are the doctors that you have to pay for because God forbid insurance cover a doctor or therapy that actually gets to the bottom of your problems.
