Guy, I get insomnia at times. For me it comes from not getting the brain sufficiently shut down and the thoughts keep going round and round. I have to read something to distract my brain before I can go to sleep. If that doesn't work I'll take a quarter of a melatonin tablet. It put you too sleep but don't take them for more than a couple days or you won't be able to sleep at all.
