I am not sure if I am already have early signs of diabetes. One time I ate a lot of cookies upon waking up and after that my eyes feels blurry while working in front of my laptop I think it happened many times already. Since then I am being careful on what I eat especially I love eating carbohydrates which has a lot of sugar on it.

Being thirsty all the time is also early sign of diabetes, extreme hunger, low energy, losing weight, numbness and tingling so if you feel this signs consult your doctor before self-medicating.
