Yes and I also have a problem with zinc it makes me nauscious and uncomfortable! I find the best and mildest form of chelation is megadoses of vitamin c! I go for the full flush at times ,beyond titeration any where up to 30 grams at a time!
I also have been through failed treatments, including anti depressent, which almost cost me my life! I find if a stay toxin free I stay Depression free. Not just copper but solvents and petrochems of any type including manty of the perfumes and colgnes out there ,natural gas and of course chlorine, from common household bleach ,deadly stuff!
