- Are you having trouble falling asleep?
- Are you more irritable and nervous than you used to be?
- Do you often have feelings of restlessness and anxiety?
- Do you feel like if you don’t get caffeine you almost can’t function?
- Do you need to drink more caffeine than you used to in order to feel energized?
- Do you go out of your way to get caffeinated drinks on a regular basis?
- Do you have frequent nausea or gastrointestinal problems like gastric reflux?
- Do you have headaches if you don’t get regular doses of caffeine?
If you answered “yes” to one or more of these questions you could be overdoing the caffeine. If you’re an adult and you’re getting over 200 mg of caffeine a day (link to the Drink Calculator), look for ways to cut back. Children shouldn’t have more than 45 mg of caffeine a day and highly sensitive or very active children are better off with none at all.
Keep in mind that many caffeinated drinks come at a high caloric price: lots of calories, little nutrition. So even if your central nervous system isn’t sending out red flags, your waistline may be. (Link to Cutting Caffeine).
