Thanks guys! DGP results came back at 18 (<20 is negative). In June 2012, DGP antibodies were 20, February 2013 they were 26, and June 2013 they were 17. So even though these numbers are hovering around the "negative" mark, I don't think they are low enough for me not to have symptoms, especially Hashimoto's symptoms. I'm on day two of close to zero supplements (I'm taking Thorne Research NAC and tryptophan because I can't cut these two cold turkey without having severe mood swings from withdrawal). I'll report back in a week or so about my progress. I don't want to speak to soon, but I think I'm already starting to see improvements.
