Hi everyone I just started working nights a couple of months ago. My sleeping schedule was adjusting fine however now I feel like I fell into another sleep pattern I can't seem to fix and I don't know how it happened. After work I have no trouble falling asleep and staying asleep when I get home around 8-830 am. The problem is on days off. I will go to bed late let's say 3:30-4 am and will always wake up at 6-6:30 am regardless of how tired I feel when I went to bed. I have no idea why that time. I then won't be tired again until mid afternoon where I then catch about an additional 3-4 hours of sleep. All I want on my days off is to sleep past 6 am atleast until 9. Everything is so messed up. It's starting to really frustrate me and starting to effect my life and day to day activities. Any advice on how to fix this??? p.s. melatonin isn't really working for me. Switching to days isn't an option at this time.
