I'm currently staying at my Uni Dorm and am sharing the place with two other guys. One of the guys is fine but the other guy...

So context, I'm a very light sleeper, so if there's a significant amount of light and sound in the room, I cannot sleep.

So my sleep schedule is virtually non-existent, I try to wake up at 6 , to get a head start for the day but cannot as this guy *begins* talking to people over a call at 11pm, no time before , everyday 11pm onwards he starts talking on the phone and loudly. I continuously request him to take the call outside the room if it's after 11 as he has the *entire day* to talk to people and I'm never in the room except when it's too sleep and i need sleep, yet he still does.

I don't think i can handle this anymore, what do I do?
