Sudden change in taste.

Hi everyone. I am new to the forum. 

My problem is that 2 days ago, liquids started to taste very differently.

First my water from the fridge tasted like very nasty tap water. I thought the filter just needed replacing. 

Later that day I drank a soda and it tasted like it had sat out in the sun then been re-cooled. Almost too sweet. 

I tried to see if beer also tasted weird. It does. At first the drinks taste normal, then they taste sweet. 

I feel fine. I don’t feel any sinus infections. 

Could I just be dehydrated?

Thanks in advance 

Can I ask if you are male or female and what your age is?

Thanks

This taste hangs happend one day to the next. Not slowly.
