I ve been caring for a fully-dependent teen son now for 17 years. He has to be watched around-the-clock for all hours that he is awake. He s not only my full-time job but he sleeps when he wants. And he may got for a week where he is awake only at night and I must forces myself to be awake, plus care for the rest of my family and responsibilities during the day. I rarely sleep more than 2-4 hours a night. I am tired all the time. It is affecting me physically now after all these years of sleep deprivation. It is basically a case of shift work disorder without the paycheck! Would a psychiatrist prescribe modafinil for these hard shifts ? I m truly in need of help for the safety of my son and my own mental health.
