Maybe twice a year, there will be a few days in a row when my mouth just tastes gross. I'm super sensitive to bad breath in others, and I can't stand it when my mouth tastes a little sour at the back of the tongue either. Why would this happen? I ate something super raw garlicky on Saturday, but it's Wednesday now! Could this still be it? Why does this happen? What can I do to change it? Again, this isn't a persistent problem, I usually taste and, I've been told, smell fine. But when it happens, it's like a few days at a time and it's disgusting. Help.
