One of the things they tell you about in Med school is the ability of certain medications to give you a metallic taste in your mouth.
Previously I had always though: “Metallic taste, that’s not that bad. I wonder why they make such a big things about it”.
That changed a few weeks back. With lunch I inadvertently had a glass of water that had come out of a copper pipe and it wasn’t until I’d finished most of the glass that I noticed the blue tint to the water and then started to taste the metallic taste. As the afternoon wore on I’m not sure if the taste got stronger or if I just became increasingly conscious of it, but it became highly unpleasant. Drinking water or tea didn’t decrease it. Eating didn’t decrease it. Even brushing my teeth didn’t help things. Eventually it disappeared (overnight I think), but it quite startled me just how unpleasant a situation it had been.
Another thing I suppose that I can learn to take people a bit more seriously about when they report it as a symptom…
