Hi guys! I'm a colleague from Romania and I have a big issue. I can't get my sleep schedule in order.

I work a 12/24-12/48 schedule. 12 hours on the day shift, followed by 24 hours off, then 12 hours on the night shift and 48 hours off. Problem is, after the night shift (which ends at 7 AM) I go home, take a shower, maybe eat something and go to sleep at around 8. I then sleep for 8 hours so I wake up around 3 PM. Naturally, I go back to sleep after some 12 hours, give or take. Now that I'm on my 2nd and last day off I wake up around 11 AM but can never manage to fall asleep at least at 10 PM, it's almost always at midnight or after and I usually get a MAXIMUM of 6 hours of sleep, sometimes 4 or even less, and to work for 12 hours after is a nightmare and very unhealthy (on the day shift I have to be there at either 6 or 7 AM). Also, after the day shift I can't fall asleep straight away, I usually collapse at 10 PM and sleep for around 10-12 hours, sometimes even more. On the night shift I have NO ISSUES. For me it's completely natural to stay awake the whole night. Do you guys have any advice? I'm already taking melatonin and it's been a huge help but it's just not enough. Thanks in advance!
