I might not be the best person to reply since it's 4:30am and I haven't gotten a wink of sleep tonight, but here it goes anyway.

For me, it definitely varies. I'm a college student and I work 20 hours/week on top of homework, so I'm busy as it is. Needless to say, as great as it looks on the resume and prepares me for life after college, it not so great on the rsd. I don't get to my homework until like 9pm on a good night (sometimes as late as like 10 or 11 though...). I am typically "in bed" by around 1am or so. It gets hard though because sometimes, I'm in pain or my body just won't let me go to sleep, despite my tiredness (like now...). I kind of catch flack over it from one of my professors (she and my roommate are the only ones who know I barely sleep, though my roommate thinks it's just because I'm so busy...professor kind of knows the truth...) because she thinks I take the "as long as your body has under 4 hours of sleep, you're okay" rule a little to seriously. I basically abide by this rule when I can't sleep. If I know I'm going to bed past like 1am, I abide by this rule since I know I won't get a full night of sleep anyway. Since they body won't go through a whole REM cycle if you sleep under 4 hours, you're more rested than if you sleep like 5 or 6 (or up to the "normal" amount). When I'm home and not at school with my roommate (love her to death and all, but it's inconvenient having a healthy roommate who goes to bed at a normal time since I don't want to inconvenience her since she didn't ask for all of this), I find that watching a movies that I've seen over and over and over again help me sleep. Since I've seen them a lot, I won't get distracted by wanting to watch it. However, it has a comforting effect on me. I don't know how you are with sleeping to noise and such though.

Medicine-wise, I have a stash of Ambien to use for emergencies only. I try to avoid taking it if at all possible because I find, oddly enough, that it helps a ton with anxiety or when my body's in a haywire-type mode. I'm on muscle relaxer 4x a day, a daily medicine to help with inflammation and chest pain, and lyrica to help with pain. This doesn't necessarily help me sleep sadly, but it does at least minimize the intensity of the "normal" pain levels as well as minimize the intensity and duration of "regular" flares, especially at night.

I know this probably wasn't much help, but yeah.
