It’s incredibly common after long-term immune issues such as chronic inflammation, pain, brain fog, autoimmunity, etc that we either have no thirst or all of the thirst. We may still drink water because we know we should, but our body never signals for it.
Or conversely, we may feel thirsty all the time and just pee it right out, like it’s not getting absorbed.
