If I have strong coffee I have problems with my breath but weak coffee several times a day seems to be okay. The same with mountain dew which has a lot caffeine. I think the effect of caffeine had different effects over different people

It is bad for your nervous system. Anything to excess is bad.  Try half calf coffee and stevia as a natural sweetner.  Stevia does not raise your blood sugar.  Try a natural vitamin as well synthetic vitamins dont have all the nutritional layers.

There is no scientific evidence to tupport that Hepatitia B is complicated by drinking coffee. Caffeine is actually used as a painkiller. It can increase your heart rate, but the latest studies indicate that coffee is not the evil drink once thought.

personally I think it is just in your head that caffeine wakes you  I myself can drink an entire pot of coffee  with loads of sugar and go right to sleep  and actually in the morning when I leave for work if I get a coffee on the road it actually makes me drowsy I have heard this from lots of people I guess its just people react differently to certain things

Caffeine is an ALKALOID.  It is a central nervous system stimulant, a diuretic (makes you pee).  It also stimulates the circulatory and respiratory systems.  The biochemical mechanisms are quite complex in the different tissues.  The cardiac effects are mediated by an increase is tissue cAMP concentration.

Many notable effects of coffee are related to its caffeine content.\n\nMany coffee drinkers are familiar with "coffee jitters", a nervous condition that occurs when one has had too much caffeine. Like tea, coffee also causes staining of the teeth. The best way to avoid this is to brush after every coffee drinking. Coffee can also increase blood pressure among those with high blood pressure. Coffee can also cause insomnia in some, while paradoxically it helps a few sleep more soundly. It can also cause anxiety and irritability, in some with excessive coffee consumption, and some as a withdrawal symptom. There are also gender-specific effects: in some PMS sufferers it increases the symptoms; it can reduce fertility in women; it may increase the risk of osteoporosis in postmenopausal women; and there may be risks to a fetus if a pregnant woman drinks 8 or more cups a day (48 U.S. fl oz or 1.4 L or more).\n\nA February 2003 Danish study of 18,478 women linked heavy coffee consumption during pregnancy to significantly increased risk of stillbirths (but no significantly increased risk of infant death in the first year). "The results seem to indicate a threshold effect around four to seven cups per day," the study reported. Those who drank eight or more cups a day (48 U.S. fl oz or 1.4 L) were at 220% increased risk compared with nondrinkers. This study has not yet been repeated, but has caused some doctors to caution against excessive coffee consumption during pregnancy.\n\nDecaffeinated coffee is occasionally regarded as a potential health risk to pregnant women, due to the high incidence of chemical solvents used to extract the caffeine. These concerns have almost no basis, however, as the solvents in question evaporate at 80–90 °C, and coffee beans are decaffeinated before roasting, which occurs at approximately 200 °C. As such, these chemicals, namely trichloroethane and methylene chloride, are present in trace amounts at most, and neither pose a significant threat to unborn children. Women still worried about chemical solvents in decaffeinated coffee should opt for beans which use the Swiss water process, where no chemicals other than water are used, although higher amounts of caffeine remain.\n\nThe American Journal of Clinical Nutrition published a study in 2004 which tried to discover why the beneficial and detrimental effects of coffee conflict. The study concluded that consumption of coffee is associated with significant elevations in biochemical markers of inflammation. This is a detrimental effect of coffee on the cardiovascular system, which may explain why coffee has so far only been shown to help the heart at levels of four cups (20 fl oz or 600 mL) or fewer per day.\n\nThe health risks of decaffeinated coffee have been studied, with varying results. One variable is the type of decaffeination process used; while some involve the use of organic solvents which may leave residual traces, others rely on steam.\n\nA study has shown that cafestol, a substance which is present in boiled coffee drinks, dramatically increases cholesterol levels, especially in women. Filtered coffee contains only trace amounts of cafestol.\n\nA study published in the Journal of the American Medical Association announced the discovery of a gene that regulates the detoxification of caffeine in the liver. Two variations of this gene exist with one variation resulting in slower metabolism of caffeine. The study compared 2,014 people who had survived a heart attack with 2,014 healthy people in the general population. For people with the slow metabolizing variation of the gene, the risk of heart attack for 2-3 cups of coffee a day was increased 36% and for 4 or more cups of coffee a day, the risk went up to 64%. For people under the age of 59, the risk went up 24% for just 1 cup of coffee a day, 67% for 2-3 cups a day, and 133% for 4 or more cups a day. Under the age of 50, the risk for heart attack increased 4 fold. 54% of th

Caffine is a stimulant. Too much can make your heart start to beat too fast, smong other things.

Maybe, but it's not likely, the amounts of sugar you describe are pretty minimal, especially compared to the amount of caffiene in the coffee you're having it with. Some people are sensitive to sugar, and when they take too much of it they become hyperactive for a while, then irritable and tired, but pretty much the same thing can happen with caffiene too.\nI'd say you have a long way to go from 8 teaspoons of sugar a day before yuo can really say you have a problem with sugar...

Chocolate contains many, many chemicals and components.  The one that seems to give most people trouble is caffiene.  Do you have this same reaction when you drink soda or coffee?

It replaces the neurotransmitter in your brain responsible for making you tired. It's the same chemical that is replenished when you sleep, so caffiene makes your body think you've slept when you haven't. If you take too much of it, it can be toxic - and habit forming.

Yes we can. Many obstain from caffine because it is addictive and we frown upon having additictions. Hope that helps =)

Yes it does.  It is directly related to the caffeine content.  Try decaf and you should be fine.  Never drink coffee if you are taking sudafed.

Caffeine does not appear to affect blood sugar when consumed in moderate amounts. This is good news since many Canadians start their day with a cup of coffee. This does not mean that people with diabetes can consume excessive amounts of caffeine. Drinking caffeine in large amounts as coffee over a short period of time has been shown to raise blood sugar. Caffeine does this by enhancing the effect of two hormones (adrenaline and glucagon). These two hormones release stored sugar from the liver resulting in high blood sugar.

Caffiene is bad! You may stay awake for an hour or so, but the sugar high leaves and then you're in the dumps without the glucose. If you really think you need little sleep, then sleep during the day.

A lot of decaffeinated coffee isn't really decaffeinated. I saw a story that a news team did where they took samples of several different "decaffeinated" coffees, some of which contained as much caffeine as a regular cup of coffee. I wouldn't trust a cup of "decaffeinated" coffee.\n\nOne to two cups of regular coffee a day can be good for you but be careful what time of day you drink it to minimize anxious feelings or insomnia.

Though some coffee drinkers develop a tolerance for caffeine, those who don't may be sending up their blood pressure with each cup, new research suggests.\n\nIn a study of regular caffeine consumers, researchers found that many persistently showed small blood pressure spikes shortly after a large dose of caffeine -- even when that dose came after several days of high caffeine intake.\n\nhttp://preventdisease.com/news/articles/062305_caffeine_bp.shtml\n\nCoffee also has an incredible effect on stress.  Try kicking caffeine for a week, and you will see your blood pressure, adrenaline levels and overall stress drop, according to a study by Duke University Medical Center.\n\nThe new research found that the effects of caffeine stay in the body all day long, amplifying any feelings of stress. Moreover, the perception of stress increased for the 47 study participants after they took caffeine tablets. \n\nhttp://preventdisease.com/news/articles/caffeine_affects_stress.shtml
