Hi everyone! I don’t know what’s wrong with me — my tongue can’t taste anything, absolutely no taste. I even tried plain salt, there’s no taste, same with sugar. I specifically added a lot of sugar to my tea but no result, I can’t feel taste or smell at all. What should I do now? On top of that I have toxicosis right now, I feel awful because I can’t taste any food or smell anything, what should I do ???
