I used to think I was sort-of addicted to coffee because I so often felt the need of a mug of it, but years later I came to realise that I had simply been abnormally thirsty. - It was prescribed medication that had made me so very thirsty.
Sometimes you are prescribed a drug and told that it may cause 'dry mouth' as a side-effect. Sometimes neither 'dry mouth' nor thirst gets a mention. - Anyway, if you are finding yourself drinking a lot more, feeling a lot more thirsty day after day than you used to, wondering, as I did, whether you are becoming addicted to coffee or tea or some other beverage, maybe you too are actually experiencing a side-effect of some medication you are taking. - If that is the case, there is a strong chance that you are gaining weight, and gaining weight quite quickly.
The weight gain is from extra fluid (salt plus the water that accompanies salt/sodium). This extra fluid is held in your blood stream, causing the veins to be a bit/lot more swollen/dilated/distended than previously. - You have become 'sensitive to salt'.
The good news is that if you avoid eating salt and salty food, you will not only lose a lot of that excess fluid and so lose weight and have more energy, and improve your health in countless other ways, but you will also find you are not feeling compelled to think about food and drink all the time, and you may stop being 'addicted to coffee'.
