Are you eating dark chocolate at night time, just before you go to bed?

Do you know there is more caffeine (100mg) in 100g (3.5oz) of dark chocolate than in a can of red bull (82mg).  Even if you only eat a few chunks of dark chocolate at night  it is still likely to affect your deep and REM sleep.

Put it this way, would you take a few sips of Red Bull before going to bed and expect to get a good night's sleep?
