Insomnia?
Just Go To Sleep
And Forget About It

It should be obvious, but some people forget that coffee is not the only drink containing caffeine. Tea (black, not herbal), chocolate and cola drinks are also high in caffeine.

Alcohol may feel like it's soothing you, but all it's doing is stupefying you. Research has shown that alcohol upsets sleep, preventing a deep rest. Same with tobacco. Avoid them all.
