To keep it short and to the point, I normally drink between 1-2 gallons of filtered water every single day. It's either sourced from my fridge with a good water filter, or in the 5 gallon jugs you pickup.
I've noticed for the last few days, maybe 3-4, that the water "feels" different. It's hard to explain, but to try and get my point across the best I can, it feels "sharper" and has a very slight tingle on the sides of my tongue. It almost feels electrified in a way, if that makes sense.
Am I the only one?
It's very odd to me, and it's not something that I "just picked up on" as i've always been a very heavy water drinker, and nothing else has changed in how i'm getting it/using it. I would have noticed this a long time ago.
Are you saying both your fridge-filtered water and your five-gallon jugs are tasting metallic? I could see one or the other occuring, but, if both are, you're the common denominator. Are there dietary deficiencies (minerals, vitamins) that can leave someone with a metallic taste in their mouth?
Try a search (ddg or brave, etc) on "metallic taste in mouth". Below is one decent article.

It's definitely not a metallic taste, I've tasted that before and this is different, it's very hard to explain. I can feel a very slight tingling on the sides of my tongue, almost the same feeling you get with carbonation.
Again, you're the common denominator here so you need to look closely at your environment and your food-beverage-supplements-medication intake. It's great that you're in tune with your body to notice when something is off.
You might have caught a mild case of the latest contagion (eg C19V4 or whatever permutation we're up to now). I've heard that loss of taste was very common with the various versions of the C19 contagion so maybe your symptoms are either the start of or a low-grade case of that. Has your taste otherwise been affected?
With medications and supplements it may not be that you've changed anything with them, but either a build up over time or some other mineral (due to food &/or beverage consumption) was added/decreased which would affect this particular symptom. You might have an allergy to something. Have you changed toothpaste brands or did they change their formula? Just going through some possibilities. Also do a search on "tingling sensation on tongue" (vs metallic taste) and see if you can get anymore info that might pertain to you.
Good luck, in any case, and I hope it disappears.
Nothing in my diet or supplement regimen has changed. To test to make sure I wasn't going crazy, i've drank bottled waters to see if I had the same result and it was normal with no weird feeling.
I have no other symptoms, or loss of taste. I did catch it last year, and lost my sense of taste for about 2-3 weeks though. Other than what i'm picking up on now, no other symptoms and I feel just fine. I'm healthy as a horse, so this caught me off-guard.
Okay, so this is an important clue. Do you know if the bottled water at your workplace is sourced and/or processed locally? If both your town's water source and the five-gallon containers' source had some change in processing (eg hypothetically they decided to add a step or a substance during purification) it might be affecting you. They usually disclose these types of things in a newsletter that comes with your water bill, but call your town's water utility and see if they've made any changes.
If you are in DC, do NOT drink the water.
Long, but informative.

Also, stress may be a factor (the kind that restricts blood flow). You may be clenching your teeth while sleeping and not realizing it. Or, perhaps something bizarre like an attempted coup of one's beloved nation by a bunch of violent beasts who are hell-bent on destroying everything that's good. That would be stressful, for example.😏
In any case I'll say a prayer for you that this gets quickly put in your past with no lingering effects.
I looked into this and none of it is my cause for this. It's not that my tongue itself is tingling, but a very slight carbonation feeling. Once the water is out of my mouth, the feeling is gone.
