Follow-Up: My son has DSPS, he is 19, and he was kicked out of school because of it. Not that he did anything wrong. He was a top student. Melotonin is not good for teenagers. As far as I know, there is not much to be done. But I'd love to talk to another person for support,no one here except for one doctor who finally diagnost my son has been understanding or had any compassion for this. My son has suffered, as have I. If you feel like you can give me any support I'd love to hear from you. Or anyone else who knows someone that has this disorder. Sincerely..J. Routt
