I've started a job recently and to complete onsite training at the company HQ, I was assigned an apartment and a roommate. The problem is, even after defining multiple times my boundaries for sleeping, including sleeping early (a bit before 12) and not being able to sleep with much sound, my roommate has not been respectful towards my requests.
He is a late sleeper which I have no problem with, but frequently he will play video games without turning the music down or bring a friend over and talk loudly until 2 AM. At this point, I've tried ear plugs and have even recently started taking sleeping pills, even then have trouble sleeping on some of the worse nights.
At this point, my physical and mental health are beginning to suffer and am looking for solutions. I know I can sit down again with my roommate to talk about this, but I doubt he will listen for the nth time. I feel like I've exhausted methods of reasoning with him normally, and am looking for answers about if it would be worth it to escalate, and how to approach that situation.
What can I do to alleviate the situation?
