So, the salt testemonial-dehydration you named yourself is not a testemonial. Ok..
Next you say you easily drink 7 liters without feeling hydrated, next say you dont drink water, except for when you prepare herbal tea.. yeah.
Also you plead "Please help me and please don't close this thread. What do I need to do in order to feel hydrated without adding salt back into my diet? I also read it can have to do with the adrenal glands but how am I supposed to get a good night sleep when I'm just constantly so thirsty?"
Well, since you dont seem to accept any (of my) advices;
- I cant say other than ask your creator to make an exception for the bodily need for electrolytes like sodium. For you only.
But I must admit, that for the first time on CZ I feel tempted to recommend a visit to the doctor.
