Without jinxing myself, for the past couple months, my wife and I have been taking Vitamin C supplements, so far so good. We only take a single 500mg dose each day and it seems to help, no idea though, could just be in our head. We do eat relatively healthy. Could be a lot better. I do eat salads at least once or twice a week depending. I probably should get a face mask for work for doing brakes and whatnot, but I'm not sure if it's even worth it at this point. When I weld, I don't weld galvanized, nor do I use brake cleaner. Though welding stainless steel alloys may cause issues, so I'd read up on the particular alloy you are going to weld up to see any health hazards.
