Caffeine is that friend. The one that you should only hang out with before 2pm for after that, there is no telling what will happen, but it usually won't be good for anyone and doesn't involve much sleep.
We all have that friend. The one we love to hate. In small doses they energise us, inspire us and make us feel alive... but in large doses they leave us feeling anxious, overwhelmed, slightly nauseous and depleted.
If caffeine is your friend you will need to have some firm boundaries to keep the friendship on the happy, energised side of the spectrum.
The most common way to find caffeine is through drinking coffee. Limit yourself to three cups of coffee per day and remember it takes 6 hours to eliminate half of the caffeine consumed so you want to leave enough time for its stimulating effects to wear off before you climb into bed.
Eliminating caffeine from your life entirely will entail a withdrawal period filled with headaches, fatigue and muscle pain. Whether this is a better solution for you will depend on the firmness of those boundaries you have set.
Don't be too hard on the coffee though. There is overwhelming evidence that the right amount of time spent with this friend will actually reduce your risk for cancer; stroke; Parkinson's disease and Alzheimer's disease.
As always, too much of a good thing is just too much, but just enough could mean you find yourself with less body fat, more hair and a happier face which will be a rather delightful thing indeed.
So whether you find your caffeine from your daily cuppa, Ceylon tea, Green tea, cocoa or chocolate enjoy the quality time fully aware that you won't be able to spend every waking moment together.
