We’ve all faced that midday slump when 3 p.m. rolls around and you just can’t keep your eyes open. But should you make an afternoon coffee run, or ride it out until you can crash in bed later that evening? 

If you want to have a good night’s rest, experts suggest you stop drinking caffeine within six to eight hours of your bedtime. So if you typically hit the hay around 10 p.m., you’ll want to plan your last cup of coffee between 2 p.m. to 4 p.m.
