For the past week and a half I've been visiting my family in the USA. I'm sleeping on the sofa at my mom's house (there is a spare bed but it's an old spring mattress and really uncomfortable - the couch is more like my bed at home so I'm more comfortable here). I have still been doing my usual thing of eating right up until I go to bed and watching an episode of something on my computer before shutting it down and going to sleep. And I've actually been sleeping fine.
Part of it, I'm sure, is the six-hour time difference. My body thinks it's much later than it is, so that makes it easier to sleep. (I'm encouraging this by not changing my watch or computer time, so I have a constant reminder of what time it is back home.) But I think a really big part of it is simple daylight. As I said before, in Prague I live in a basement apartment without any real daylight to speak of. Here, I'm sleeping on the sofa right in front of the window. When the sun comes up in the morning, it hits me. Even if it's overcast (as it is today), the natural daylight is still a hell of a lot brighter than the awful fluorescent lights in my flat (the awful kind with the long skinny bulb that you see in supermarkets). I'm still not going to bed early, and I still lay awake for a while thinking and talking to myself before actually going to sleep, but it seems like once I finally decide I really want to sleep, I doze off without too much trouble. I have been waking up a few times during the night but that's only because my mom's dog is really possessive of me now that I'm back and insists on sleeping *on top of* my legs to make sure I don't go anywhere in the night. This makes my knees sore after a while and I wake up and have to change position.
So that clinches it for me. When I get back, I'm going to start looking for a new apartment. I've been considering it for a while, since this place has a mold and dust problem and we still don't even have heat (the basement was never designed to be lived in so there's no built-in heating and we have to use space heaters which are too expensive to turn on until it's really necessary). I'm also having some troubles living with my current flatmate. I'll miss living with him overall, but I've been feeling a lot happier during the time I've been here, and I don't normally enjoy visiting my family so that's really saying something. The darkness in that place has obviously triggered seasonal depression a lot earlier than I would normally get it - I started having these problems like six months ago, and now I'm sure of the cause.
