WASHINGTON (CNN) — According to the FDA, about 4 in 5 adults in the US consume caffeine daily. But, it’s important to know when to stop so your sleep isn’t affected.

“There’s definitely some health benefits, but there’s also some drawbacks if people take in too much,” commented nutritionist Liz Weinandy.

Drinking too much caffeine can make you jittery, anxious, nauseous, increase your heart rate, or give you a headache. But, it can also lead to insomnia.

Weinandy says caffeine affects people differently depending on body weight, medications, and sensitivity.

But as a general rule, “Not drinking coffee after noon, around 12 pm, is a good idea to make sure it’s out of a person’s system almost entirely before,” heading to bed.

For healthy adults, the FDA recommends consuming no more than four or five cups of coffee (400 mg) a day. Keep in mind coffee isn’t the only source of caffeine. A 12 oz soft drink can have 30-40 mg, 8 oz of green or black tea contains 50 mg, and an energy drink can have anywhere from 40-250 mg of caffeine.

Your caffeine intake should be spread out throughout the day and not be consumed in one sitting.

If you think you’re taking in too much caffeine, cut back gradually.

Weinandy said, “Tapering down over a week is ideal. If you decide to go cold turkey, it’s really — most people will have a headache, they’ll have some increased drowsiness, but usually that only lasts for a couple of days.”
