adhd? if I wouldn't set artificial constraints forcing my sleep-wake-rhythm into a frame it would probably rotate continuously. let's say you catch me at 1am to 9am. next day it would be 1am30 to 9am30. next day 2am to 10am etc ... I'd fight against my urge to sleep forcing the rhythm to move like that. now how to learn liking to go to bed? that's my 1 million dollar problem - paradoxically I very much like to _stay_ in bed ...
