Well, I was waiting for the adverse reactions to start after having my first 2 amalgams removed Thurday. They did...Friday morning I started getting "headachy" and irritable. I remembered what I had read on this forum and the stories, so I took 1 mg of vitamin C. I was feeling better within about 20 minutes. I had to take extra on Saturday and Sunday as well. Today I feel okay, but know I am not out of the woods yet. I have my vitamin C with me at all times!
