Constant Urge to urine(sometimes only a bit), uneasiness, rare vision changes, dry lips and thirst.?

Well the good news seems to be that you definitively are not suffering from diabetes. it is obviously impossible to give a diagnosis based on the symptoms you mention without further ysis; I would recommend you consult an endocrinologist and have your pituitary, your thyroid and your adrenal glands checked. Also have an ophthalmologist check your retinas. All the best.
