Right, so the mode of intake matters, not just the salt itself.
For example one could eat bland (unsalted) food and drink salt water later which would produce less pleasure for the same quantity of sodium consumed. So there might be different physiological effects.
i find adding some soysauce to a cup of water and chugging that before bed takes care of most side effects.
and food does taste better with salt added, i must admit, esp. meat.
