My insomnia is, annoyingly, pretty hard to beat. Part of it is genericly caused, and part of it is delayed sleep-phase syndrome, both of which can be helped by various well-known practises, many of which have already been mentioned here - however both my job and my life means I have days when I don't get to bed until 3/4am, which screws me up.
My bigger problem though, is that even if I can take care with the physical Insomnia, I also have mental insomnia. I find it impossible to clear my head, and that regularly keeps me up until a couple of hours before I wake up. I'm unable to sleep while my brain is thinking of something, regardless of how boring it is (until the point that my body is just so tired I can't stay awake, which is when I fall asleep), and if I manage to get my brain to a state when it could sleep, suddenly it instead thinks "but what about.." and returns to the topic that's interesting enough that it keeps my brain running in circles, unable to stop concentrating. Really annoying.
