When I was growing up, I had to share my room with my older sister for a while, and she liked the radio playing. My girlfriend likes the fan on for background noise. Both kinds of sound are hard for me to fall asleep by, though the radio was worse. At least the fan is consistent. Her snoring, however, is not.
I find the two things that make it hardest for me to sleep are a busy head and the physical discomfort of the sensations I feel while lying in bed. I have to readjust in minor ways for quite a while before my body calms down enough for me to rest. I'm surprised my girlfriend has never complained about this in all the years we've been together - not even once - not even if I need to do it while we're curled up together, which means I have additional pressure on my body to deal with and am squirming around even more! I always knew I was doing this, but it wasn't until last night that a little light went on in my head, and I said to myself, "Ah! Sensory issues!" (The "little light" didn't keep me up, though. )
If I'm in the same position too long, especially if it's without sleeping, I have to turn over, or else I get nasty pain in my hip and/or shoulder. Sometimes turning helps. At other times, it just gets me more awake. If I need to adjust my position, whether in a large or small way, and I find I can't for some reason, that drives me nuts and really prevents me from going to sleep.
In this regard I have no clear idea where my fibromyalgia is distinct from what may be Asperger's related sensory issues.
Wanna have a really hard time sleeping? Try it during the day, after you've had to move back in with your parents for a while, with the TV blaring downstairs, with your mother having chatted with you before you turn in, so that your head is busy and you have less time than ever (cutting into your five hours or so) to sleep before taking an awkwardly scheduled bus system back to your night job, where you work a lot of overtime and have to deal with a harassing coworker. That's what I had to do when I was 18. That was rough. The environment at home was always stressful to begin with, and this made life so much harder to manage. But my mother really missed me, so I never stopped her from talking to me. I just dealt with it. (She passed away in 2001, after we'd worked out a lot of stuff and had become friends, so I'm not sorry for the sacrifice I made in letting her talk.)
