Good to hear that you are improving, Glenn. Years back I used to do a lot of welding on heavy equipment and quickly learned to avoid those fumes.
As for the old trick of drinking milk to avoid getting sick from welding galvanized material, yes, it works, but is no help for the rest of it. Despite that, avoidance is the better option. Similar to the old adage that "an ounce of prevention is worth a pound of cure."
