Meditating as sleep aid Every book that I have read about Buddhism and medititation says that, as meditation cultivates concentration and awareness, one should never fall asleep while doing it. 

So, what about when I cannot sleep? Can't I meditate to help me sleep, or only before I go to bed?

(I mostly practice Vipassana meditation)
