'Light' bedtime reading

Lately I haven't been able to sleep at all well, I either can't get to sleep or I wake up and can't get back to sleep! I blame this on several different things mainly exams and school related issues but at the end of the day I can blame it on whatever I want , it still won't change the fact that I can't seem to sleep!

When I can't drift off I try and read the Economist as most of its article's contain long , ludicrous words which apparently help me to fall asleep.

Have a good nights sleep-if that's possible!
