Why did I wake up with a black tongue?!

Question: Why did I wake up with a black tongue?

The only unusual thing I did prior to that was chewing 4 Pepto Bismol yesterday. Is there a correlation?

Answers:

The active ingredient in Pepto-Bismol contains bismuth. When a small amount of bismuth combines with trace amounts of sulfur in your saliva and gastrointestinal tract, a black-colored substance (bismuth sulfide) is formed. This discoloration is temporary and harmless. It can last several days after you stop taking Pepto-Bismol. Individual bowel habits, your age (the intestinal tract slows down with age), and the amount of the product taken all help to determine how long Pepto-Bismol is in your system.
