I recently got in a similar cycle by accident. I was up all night on Saturday then when I tried to take a nap at 6pm on Sunday I ended up sleeping until 6:30am Monday. I've been enjoying waking up at 6:30 every weekday since then and it's working out great. I get to do all the things I usually wanted to do in the evening but never got around to (like hit the gym).
