For a good night's sleep
Different people can react very differently to caffeine
Many of us start our days the same way: with a cup of coffee or tea. Caffeine is as much a part of our routine as brushing our teeth or getting dressed for the day.
Maybe your habit extends to a cup of coffee in the afternoon, or you have a soda with your dinner.
And maybe as a result, you lie in bed awake later thinking of where you went wrong instead of getting needed sleep.
