5. You drink too much coffee
If you rely on caffeine to get through your day, you can develop a dependence—so without it you can go into withdrawal, needing several cups of coffee or tea just to feel “normal.” And the worst point of withdrawal? Right in the morning. To make matters worse, caffeine can still course through your system when you’re sleeping if you’ve had any coffee or tea in the evening, which can interfere with normal REM sleep and leave you feeling even more tired. An easy solution is to cut back on the amount of caffeine you consume during the day and steer clear of caffeinated beverages within hours of your bedtime.
