Love the thread, I get two weekly insomnia, I sleep when I take far more meds than I'm supposed to bet thTs just dangerous!
Some things I do when I really can't sleep, I realise quite early on that I'm not gonna be sleeping that night, so I mentally prepared for it, is say to myself "you're not gonna sleep tonight, so stop trying and stop getting stressed about it!"
As for things to do, it's normally watch shit films on tv, or play RPGs like monsta has mentioned, skyrim is a good one, pick that up and it will be light on no time!
I understand books expsensive or even free if you join your local library!
I love to be able to make things easy for you CK but thats not easy in it's self!
the worst part of insomnia for me is when your tossing and turning and you just cant get comfortable or nod off! Thats terrible for my mental health, that's why fore it's best to get lit of bed and find something to do!
So to summarise, join the library, play RPGs accept the rack you not gonna sleep that night early on!
How many nights do you go without sleeping properly, I do a bout 3 to 4 nights quite regulary and feel like shit afterward, psychosis starts to creep in!
I'm sorry you going through this CK, I know you won't but I'm always here to pm

take care mate, also congrats if you can get on the sub
