I'm having the same problem as you. I woke up today at 15:30 PM. I'm still awake now at 2:15 PM. It's going like this almost 3 months straight already. Sometimes I dont sleep at all for 30 hours +- or so. I dont like it either, I tried many times waiting till next day 10 PM and then wake up early but it doesnt seem to help
It feels like I'm living American times in Europe.
