Quit caffeine entirely for a week or three. You may have some withdrawal symptoms, such as headache for a couple days, and lethargy for a while, but when you go back to caffeine, you'll find that very small amounts will have a profound effect on your system. ;)
Of course, getting your caffeine from Dew or any other soda also means a sugar high is part of the equation, and a lot of calories, but that's a whole 'nother kettle of fish.
The problem with caffeine is that, like any other drug, we build up tolerance to it over time. The best way to re-gain the beneficial effects is to quit for a while and flush the system out.
Of course, saying caffeine is beneficial is sort of like saying steroids are beneficial. Certainly it 'speeds' us up, but it does cause issues in the long term, especially as your intake increases. |
