Hi everyone Before 2 hours. At 6 AM. ( i ate a heavy meal at 2 am ) I was walking outside for a short time like 5 minutes then all of a sudden felt tired, started shaking and sweating a little bit, tachycardia and nothing else. I couldn t stand so i went to my bed and it did t disappear for like 30 minutes , then i slept while shaking for 2 hours and i am feeling better right now. I didn t eat till now ( i can last for a day without eating and that did t happen ). I walk every day, run every day. I m 21, no health problem ( just atobic asthma), non of my relative is diabetic. ( no fever, loss of consiousness, stress or blurring of vision or chest pain ) i m not taking any medication.
