I have not really had problems sleeping, I feel as if though I choose to stay awake, not that I cannot sleep. I am able to get to sleep quite easily when I want to, but when I feel I should and I cannot, I may have a light snack (the increase in insulin will knock me out sometimes. I know this is not the healthiest option, but it helps if it's only something light), write down anything that is worrying me (so I can worry about it when I wake up, I don't have to think about it while in bed; I know this sounds weird, but it actually works), or I read something really, really difficult to understand which normally tires me out mentally (and if I was able to understand it, then all the better -- I've learned something new!). If not, then I might stretch for a little bit which will normally relax me enough to get to sleep.
