How much did you sleep before. I'm reading these kinds of threads and finding lots of similarities with my life. I generally sleep 10 hours a day and have trouble getting out of bed.
I would delay sleeping to 3am, and then need to get up for real life. Over time it became a real sleep debt. So around 6 hours typically. Delaying going to sleep and getting out of bed are signs (but you need to collect many signs of ADHD to be diagnosed). Some people keep pills by their bed so they can do that even if they can't get out of bed.
Apologies for the late reply, HN doesn't really notify me
