I know I can do it. The problem is I can't do it when I live where I do now, because I just do all I can to block out people talking / not murder people and break stuff. As soon as no one's awake / in the house (and I've had a few hours to "calm down" from the stress of the day) I get really productivem so I really think it WILL happen naturally... once I get out of here.

I sleep fine as long as I haven't accidentally eaten any processed foods! If I eat something processed I get insomnia, wake up tons, have trouble falling asleep and/or get nightmares. Now I'm being super strict with myself until I go to Japan too (I want my mood/skin/etc to be the best possible right before going, so I don't arrive and immediately seem like a gross crazy depressed person) so I'm just eating like, sausages and kimchi and bananas and not letting myself try any new potentially-risky foods/brands.
