The first thing to do when thinking of purging caffeine from your system is to remember that it may not be possible to get rid of it any sooner than usual.
But remember, the half life of caffeine, or the amount when half is gone from your system, is up to 5 hours. For some people, it's less.
So you probably won't have to put up with excess caffeination for very long if you have indulged in too much coffee or energy drinks.
If one afternoon you quaffed several big mugs of java and took more than 400 mg of caffeine, which is not recommended , for many people the stimulating chemical will most likely be gone by morning.
If you get rid of the caffeine, you very well could experience a slump in energy and alertness. If you are thinking of quitting altogether, you may need to slowly wean yourself off of your daily caffeine intake so you don't get headaches and feel drowsy.
It’s not possible to eliminate caffeine from the body more quickly than usual. Caffeine’s half-life, the time it takes to for a healthy adult to see a reduction of caffeine’s presence in the body by half, is 5.7 hours. And if you don’t get your usual dose the next day, you may go into minor withdrawal and be groggy and cross. Some people also experience a headache if they don’t get their usual dose.
Some people go to extraordinary lengths to eliminate caffeine, including doing vigorous exercise and taking cleansing or detoxification measures. These measures are not likely to reduce caffeine’s presence in your body at all. Be patient, the last traces of caffeine should be gone completely about a day after ingestion.
Dr. Ray Schilling says  the elimination of caffeine from the body takes about 28.5 hours. Complete elimination occurs after five half-lives.
As Mental Health Daily says , it takes on average about 1.15 days to eliminate the caffeine entirely. But after 10 hours, most people have only about 25 percent of the caffeine they started with.
Mental Health Daily warns that for some people, it make take up to 2.18 days to eliminate if they metabolize the caffeine slowly.
Different factors affect how long it will take to purge the stimulant. Mental Health Daily says:
There are a variety of factors that can impact the time caffeine stays in your system prior to clearance. Examples of such influential factors include: individual attributes (age/body mass/genes/health), co-ingestion of other drugs/substances, dosage of caffeine consumed, and how often caffeine is ingested. Understand that certain factors may be slightly more influential than others, but are largely subject to personal variation.
Understand that for most healthy adult caffeine users, caffeine should be fully eliminated (100%) from a person’s system within 1.5 days. Its metabolites with longer half-lives (e.g. theobromine, theophylline, etc.) may remain present in the body for nearly 2 days. Most caffeine users will have cleared caffeine and its metabolites from their bodies within 48 hours.
Healthline says both theobromine and theophylline are stimulants . They act specifically to stimulate the heart. They are in tea and coffee.
Theophylline relaxes smooth muscles in the airway, making breathing easier while also stimulating both the rate and force of heart contractions.
Theobromine can also stimulate the heart, but it does have a mild diuretic effect and improves blood flow around the body, leading to a net reduction in blood pressure.
The amounts of these substances in a cup of tea are very small though, so their net effect on the body is probably negligible.
Some of the caffeine you ingest is metabolized into theophylline and theobromine, so every time you consume caffeine you will indirectly increase your levels of these two caffeine metabolites.
Say you have a big meeting or exam the next day, and you foolishly over-caffeinated when you need to get a good night's sleep. Or you have the jitters, sour stomach, and a racing heart from too much of a good thing.
Several articles on the Internet give tips on how to de-caffeineate, so to speak.
Face it, if you have caffeine, you might be stuck with some in your system for a whole day. If so, this video shows how to overcome the jitters.
The one on WikiHow.com has 12 steps , some of which we synopsize below here:
And remember, it is only common sense to stop ingesting caffeine if you want to purge it from your body. Chocolate, green and black tea, of course coffee, some over-the-counter pain medications, and many other substances contain caffeine.
Read labels for caffeine content or do an Internet search to see if something contains caffeine, and stop hitting yourself on the head if you have a headache!
If you need to get your caffeine but don't feel like you can drink coffee, tea, or an energy drink, try Viter Energy Mints . The mints are sugar-free and freshen the breath, plus they contain invigorating B vitamins.
Each mint has 40 mg of caffeine, so you can eat several before you hit that daily recommended wall of 400 mg.

Erectile dysfunction. In combination, those are two of the ugliest words known to man. But can caffeine help you get it up?
Science hasn't found the definitive answer to this question, but one study concluded that fewer men who consume caffeine have problems performing. The study said:
Caffeine intake reduced the odds of prevalent ED, especially an intake equivalent to approximately 2-3 daily cups of coffee (170-375 mg/day). This reduction was also observed among overweight/obese and hypertensive, but not among diabetic men. Yet, these associations are warranted to be investigated in prospective studies

Many breastfeeding mothers wonder if it's OK to take caffeine. In fact, many nursing mothers just avoid caffeine in case it would keep their babies fussy, jittery and awake.
The answer is yes, you can take caffeine while breastfeeding, as long as you don't go over about 300 mg a day.
It's an important question because caffeine is in so many products, and taking coffee, tea, or soda is such a common ritual.
And breastfeeding mothers may be tempted to take caffeinated products because they are deprived of sleep by their newborns' odd sleep schedule.
