Night person. I have lupus, and the only symptom I have is photosensitivity, a fancy name for being ultra sensitive to sunlight. If I spend more than a few minutes in the sun, I will jaundice, and my inner wrists will look rusty. It can lead to facial rashes which can keloid. So, now I can stay out of the sun with good reason. I have really always been a night person. When I was younger and living with my parents, I would pace the floor when it got dark and I was stuck in the house.
