Sleep stealing culprits

Sleep! Is it as hard for you to get to sleep some nights as it is for me?  There are nights that I can not hold my eyes open by about 2 am.  :)  And then, other nights, I try the same things and stay awake half the night! 
I've talked about wind as a sleep stealing culprit .  What other things are culprits in your world of sleep? 

Caffeine can steel my sleep easily!  But, that's a common issue.

Another culprit to my sleeplessness is:   a social event late at night!  I guess I should expand on that one.  I have noticed that if I am out socially and I get 'riled' up, as in laughing, carrying on, talking a lot, I guess dancing would be among them if I could/would dance.  Going to a movie with my husband doesn't usually bother me because its not much different than watching a movie at home.  But, if it were a loud, action filled movie, it may keep me up.
A concert would definitely bother me!  I Have been to a total of maybe TWO concerts in my 15yr life w/RSD.  It was one of the activities that I cut out when I was first dxed to keep my pain as low as possible.  I have found it painful and the after affect pain is worse.
  Any kind of travel also causes sleep deprivation.  I wonder if I should get some sleeping pills for those nights I really need/want to do something and know it could keep me awake.  Doesn't matter how tired I get because of said activity...

Why would this happen do you think?   IMHO...I believe that our nerves get 'fired' up whenever we are active.  Do you notice it being harder to 'settle' down after being really active?  You are so so incredibly tired, but still can't sleep!  I have found I must relax IN BED for a long while before actually getting to sleep. So, why don't I go to bed earlier, take my meds, read or watch tv in bed till hubby comes to bed.  Hmmm....cause now we don't have cable in our bedroom and those dumb shows I want to watch are on till 11!  Thats typically why! But, I do hope to work my way earlier and earlier.  Right now, I fall asleep about 2, sometimes 3. On a rare occasion, I can fall asleep before 1am!

 Oh, and what if I go to bed early and having forgotten to put the dog out one last time?  I get up, go put him out and the nerves are starting to rev up again and it takes even longer.  I hate when I'm just about asleep for a nap and then must get up again!  The nap is sometimes a lost cause!
