I eat salty potato chips.
One salt is certainly like the other. Not sure how your body reacts to salty potato chips, but I would try a very balanced diet of old fashioned cooked potatoes, beans or Brussels sprouts and a small t-bone or steak, if I were you.
And a visit to a doctor if nothing helps (after 1~2 weeks) . You might have diabetes if you're that tired and thirsty.
