By that definition, hydration is addiction. Refined carbohydrates (sugar, flour) are definitely addictive. If you have the normal modern diet full of sugar and flour and you quit them cold turkey, you will be sick and miserable for a few days, while your body adjusts. And if you quit carbs enough to go into ketosis, and then "cheat", you'll be right back on the insulin-spike bandwagon. (This is not to be construed as an argument in favor of keto diets, or against carbs!) And unlike water, your body does not need refined sugar or grains. You can live just fine on meats and vegetables.
