It's not like I'm up partying until 4am. I'm usually just laying on the couch. I'm not preventing her from making noise either. I told her she can kick me out any time she wants if she feels bad about making noise and I'm sleeping, and I wouldn't mind being woken up during the day, as it's day and I probably should be up. I'm at the point I'm sleeping through everything anyways. Before I started spending a lot of time here I would be sleeping at the library through other people fighting, EMS coming for bathroom ODs, and whatnot. I tell her she has total control over her place, and I am quiet when she's sleeping.
I do want to get a regular schedule though because it's helps both my mental and physical health.
