I have DSPS

it’s a self diagnosis.

….they find it very difficult to wake up in time for a typical school or work day. If, however, they are allowed to follow their own schedules, e.g. sleeping from 4 a.m. to noon, they sleep soundly, awaken spontaneously, and do not experience excessive daytime sleepiness.

Life would be near perfect if I could sleep from 4 a.m. to noon.
