Is there a way to reduce the quantity of caffeine on your body, like an antidote?
For example, if you take an expresso or a certain amount of coffee to keep you awake (for finish a work or study), but then you realize that you don’t need to be awake all night, is there something that cuts the effect of caffeine (food or drink for example) you have on your body?
I’ve searched in your FAQ, but didn’t find anything.
Thanks in advance
The best answer is: time and planning. Setting a time limit on caffeine consumption (such as last drink by 4 PM) can help to ensure you’re mostly free of caffeine’s effects by bed time. You should also plan you
A healthy adult’s half life for caffeine is approximately 5.7 hours (see: NIH). If you take an average 1.5 oz espresso made from 7 g of espresso beans that contains 77 mg of caffeine at 8 PM, you would still have almost 40 mg in your body by 2 AM! Yikes.
Smoking has been shown to increase the metabolism of caffeine (source) from about 6 hours down to 3.5 hours, clearing it out of your system faster. This however, introduces nicotine into your body, which is another stimulant, and is just terribly unhealthy.
Studies on rats suggest that a chemical known as Rutaecarpine may increase the rate at which caffeine is metabolized, in rats. While this is yet to be studied in humans, herbal supplements have popped up on the market containing Rutaecarpine that people can take at their own risk.
Ultimately, you’re best off planning your hard work earlier in the day rather than relying on caffeine to keep you up. If you absolutely need to have something done for the next day, it’s better to sleep now and wake up early, have that loving cup of coffee to get you alert, and get the work done early in the morning.
