If you want to lead a truly healthy life, it is best that you avoid all addictive drugs, no matter how socially acceptable some of them may presently be in our society. Caffeine in all its forms in coffee and sodas, and many teas too, is one of the primary socially accepted addictive drugs that a person might incorrectly feel is not a serious problem. Yet it is now scientifically accepted that caffeine is a very unhealthy, addictive drug that creates a strong dependence, not just chemically, but psychologically and behaviorally too, and one which can lead to strong withdrawal symptoms. Many unhealthy and sleep deprived people feel they cannot function without their regular morning coffee, and without an ongoing ingestion of caffeine during the day by either having more coffee, or by having caffeinated sodas, as they go through their workday. The truth is that a moderate caffeine user, whether it is in coffee, or another type of food, is a rare individual. Caffeine is so addictive that most consumers of it end up consuming a lot of it. 90% of Americans consume caffeine every day. If they try to suddenly stop, they get terrible, splitting headaches as blood vessels in the brain dilate. So people are quickly driven back to taking more caffeine.
Caffeine is much more addictive and much more of an actual drug than the general public is willing to fully admit to themselves. Yet, anyone who misses their regular coffee or sodas will tell you that they experience typical signs of substance withdrawal. These may include headaches and irritability, and the inability to function in their usual manner. You may not know this, but every can of soda, except for specific non-caffeinated ones, contains about one quarter of the caffeine in a cup of coffee. Diet sodas, you may be surprised to learn, contain even more added caffeine than the regular ones. This could be compensation by the soda companies, who are well aware of the psychological effects of their products on people, for the fact that diet sodas do not provide the stimulus of the usual high sugar content of the regular sodas. This extra caffeine is added specifically to create a drug effect, making the soda even more of a stimulant that keeps people coming back for more. This sells more soda but undermines the health of the consumer by using a harmful drug that is known to cause a physical and psychological dependence. Even though soda companies say that caffeine is put into their products for its taste, most people when tested cannot taste the difference between the same soda with or without caffeine. The great popularity of caffeinated soft drinks is driven not so much by subtle taste effects as by the mood-altering and physical dependence of caffeine that drives their daily self-administration. Subjectively, people report that the caffeine in sodas gives them a "lift." Temporally they feel less drowsy, less fatigued, and more capable of rapid and sustained intellectual effort. A common example of trying to utilize this effect is when students who are trying to get by on an inadequate amount of sleep, eagerly purchase energy soft drinks containing a great deal of caffeine. These are drinks that contain, on average, 75 mg of caffeine, approximately double that of a regular size coffee. Ultimately, the caffeine masks their deep need for proper sleep. Unfortunately for them, studies show that students who use caffeine to study late into the night find their short-term memory is poorer on the next day's exam.
And if you are not intending to stay up late, the caffeine is very bad for your sleep. A few caffeinated sodas, or one strong cup of coffee, drunk 30-60 minutes before going to sleep can cause restlessness and difficulty falling asleep, increased body movements during sleep, a tendency to be more easily awakened by sudden noises, and an overall decreased quality of sleep.
The best way to deal with substances of this nature is complete abstinence. People who use it generally are dependent on it to function in their day to day life because they have not been taking proper care of themselves. It is often a compensation for run down overall health because of poor nutrition, failure to stay fit, and most of all, inadequate sleeping regimes. Its use leads to more deterioration of a person's health, and with its continued use, their health is liable to continue to deteriorate further and further.
Anyone who is seeking optimum health should stop drinking coffee and other forms of caffeine, such as caffeinated sodas and caffeine containing teas. Caffeine is a drug and the last thing any of us needs is the regular use of an addictive, physiologically deleterious, mind altering substance in our lives. If you are physically addicted, you will need to endure the withdrawal symptoms for several days while consuming caffeine-free substitutes. It may be of interest to you to know more about why you get a headache when you skip your morning cup of caffeine. Caffeine acts as a powerful vasoconstrictor in the brain. That is, it constricts blood vessels, lowering oxygen flow to the brain because of the deceased circulation. When caffeine is no longer present the vessels dilate resulting in a sudden increase in circulation and oxygenation that results in headaches.
The most common caffeine withdrawal symptom is a throbbing headache, usually occurring within 18-24 hours after the last dose of caffeine. Other symptoms may include drowsiness, lethargy, irritability, nervousness, depression, and nausea. Sometimes people who are just reducing caffeine intake, report being irritable, unable to concentrate, nervous, restless, and feeling sleepy, as well as having a headache. If you're chronically tired as you gradually switch to caffeine-free sodas and teas, herbal coffee, and other alternative beverages, try to sleep more each night, eat healthier foods, and exercise regularly. While withdrawal symptoms force millions of addicted people back to the caffeine habit and make them reluctant to give it up, the good news is that people can often avoid this pitfall by very slowly weaning themselves off caffeine over a two to three week period. There is a good chance you will be able to avoid the headaches, and at the same time gradually adjust your body and mind to being less reliant on this stimulant. Cutting back by a half cup of coffee per day or having one or more less caffeinated sodas each day is a recommended pace.  . If you find yourself needing a cup of something try to experiment with caffeine-free herbal teas.
Some people might think of trying decaf during the weaning period. But it is important to keep in mind that most decaf, even some that say "naturally decaffeinated" on the container, has been made with methylene chloride, and a significant amount of this toxic chemical is left as a residue on the newly decaffeinated coffee making it unhealthy. Decaf coffee is also highly acidic and many feel that because of this it is not health promoting. The best choice is a Swiss water processed decaf. Unfortunately, drinking only decaf coffee will not free you from caffeine addiction, and may end with your eventually desiring your regular coffee, or other sources of caffeine, like commercial sodas. The reason is that, contrary to what most people think, decaf still contains a small, but significant amount of caffeine.
One product I regularly recommend to my clients who love the taste of coffee, but who wish to improve their health by eliminating caffeine entirely from their life, is an herbal coffee called Teeccino.  It comes in a variety of flavors, and most of my clients who try it find the taste of it quite satisfying and don't miss their past caffeine-laden morning cup of coffee at all. It can be brewed in the same way as regular coffee is brewed, so that you don't even have to change your morning routine. For those freeing themselves from caffeine this way, it is recommended that you gradually reduce the percentage of your caffeine containing coffee over a two-three week period until you are drinking 100% caffeine-free herbal coffee.  You should be able to avoid headaches and also gradually adjust your body to less reliance on stimulants.
The body's reaction to the toxicity of caffeine can vary so greatly for different individuals that you have to discover how it was uniquely affecting you. Some pains and discomforts you would never have thought were caused by caffeine will disappear after you quit having coffee, caffeinated sodas and other forms of caffeine. You may experience improvements in your skin, digestion, sleep, mood, and energy among others. You might very well find that three months after getting caffeine completely out of your life, your energy stays steady all day long and you feel better than you've felt in years.
