I have that diagnosis. Basically. I have DSPS with progression meaning if I let things be I tend to go to bed later and later on. I used to always be sleep deprived as a kid because I never got enough sleep, getting up in the morning for school was like torture, I just washed, got dressed and left. I could never even eat in the morning, I would have puked.

More and more my pattern is turning into the irregular type. It is kind of when you lived with DSPS and non24 for such long time what little order you have falls apart.
