Yes it burns at the plexus and throat. I find it less so when I filter the (bottled) water in a brita filter (cartridged filters) but then it tastes funny. So I actually never drink water.
What is even weirder if I drink those water bottle with a slight hint of flavor, no reflux. Might be a mental problem?
I don’t experience what you have.
Was going to use it as a background, but the artifact ruins it.
