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.

Caffeine is like everything else in this world, use the golden rule "Everything in moderation." Caffeine is a drug. In limited doses, it will do you no harm, but in larger doses you can become addicted.

Biologically speaking, caffeine impedes the speed of cell reproduction. So seeing as how thousands and thousands of dead skin cells are shed each day, we replenish our cells constantly. Caffeine also severely dehydrates you.\n\nBut as long as you watch your caffeine intake and hydrate, no problems should be too noticeable.

Coffee as you know contains caffeine. Depending on the variety used the caffeine content can vary.  This has the ability to stimulate the brain.  However, overdosing on caffeine can have the reverse affect.  Think Incredible Hulk Syndrome.  Further, caffeine and other substances within the coffee can speed up your heart, too fast.\n\nThe real danger comes from consuming, unwittingly, more caffeine from other sources, such Coca Cola chocolate etc.\n\nHowever, moderation is the watch word.\n\nMy favourite stimulant is TEA [Camellia sinensis]. I consume gallons of it everyday. \n\nOf course it does contain equal amounts of caffeine, as coffee.  Tea does have other inherent health properties.

It completely depends on the dosage and the person. For someone that does not ingest caffeine on a regular basis, it may take minutes to a few hours to have an affect. What are you doing to the caffeine that it makes you high?

Coffee is bad for you not because of the caffeine in it, but because of a chemical known as tannic acid. tannic acid is used to mold tough leather, so think about what it could do to your body. Another substance which contains this chemical is tea. However, only non-herbal tea (restaurant iced tea for example) contains this acid, but herbal tea is safe.

Coffee can often have a paradoxical effect, in which it can actually induce sleep-this occurs generally at very high doses, or in people that are especially sensitive to it.  But, as is the case with all chemicals, there is a wide range of physiological responses in humans, and you may just be immune to the stimulatory effects of caffeine-it probably has to do with the levels of detoxifying enzymes in your liver-thus, you may be insensitive to many drugs.  This is something to be aware of if you are ever ill and need medication.

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

I have been searching and all the literature and the side effects listed are all short term, there is no mention of long term effects.  I would think that the experts know very little about this as Ritalin is a relatively new drug.\nYou have been on some pretty serious drugs in a short time frame, maybe its the combination rather than just one drug which has caused your problems.\nI feel for you, its rotten on top of the problems you have already had.  I hope you find a satisfactory answer to your question...good luck x

there are traces of caffine in decaf coffee.  If you are not a regular coffee drinker, the decaf can stimulate you.  If you begin the regiment of drinking decaf regularly, then you will have to up grade to caffinated eventually.  I suggest not to drink coffee unless you feel you need it.
