Hi , thank you for your question. I hope others may be able to chime in to share their experiences. Have you already tried gum? Also, you probably have, but if you haven't, it might be worth mentioning to your doctor. They may have some other suggestions as well. Please keep us updated if you find anything that helps you neutralize the metallic taste, as I'm sure there are others who can relate. Best, Minel (Team Member)
