Has anyone experienced reactions to caffeine?

Question

I've never really had any reactions to caffeine but lately when I drink it I get very jumpy and nervous. What might have caused this change in my bodies reaction to it?

Answer 1

erm, excessive consumption.

Answer 2

Yes.  Have you lost weight or not eaten, added a new RX or vitamin, allergy med  or some OTC preparation you are not remembering. I cannot drink coffee/cola when I take Comtrex, etc.  Plus, ff you are already anxious about something, coffee could exaggerate the tension.

One other suggestion - had you changed the way you prepared the coffee or the coffee itself. (robusta beans have about twice as much caffeine as arabica, light roast has more than dark roast -so check your container, you might just be getting more caffeine than usual .)

Note - In movies/ads you see sophisticated diners having after dinner coffee - do these people go to sleep or catch the red-eye. A coffee at dinner would keep me up bleary-eyed till noon the next day. Even de-caf contains a tiny bit.

Answer 3

dehydrated... easily bad-tempered.. getting mad for no reason.. somehow feeling addicted to how the coffee made my body reacted in a peculiar way... you know.. verry bad!

So I try to limit my coffee habit, I mix it with milk sometimes

But now I don't anymore,, I tend to be vegetarian.. I support having a good eating habit yet not making us overweight..

Answer 4

Caffeine is proven to cause anxiety. People who get panic attacks or have anxiety disorders are told to avoid all caffeine substances, and some people are even cured of their anxiety problems if they cut it out completly.

I can only drink coffee or tea in the mornings, if I have more thoughout the day, it makes me feel jittery and anxious.

Answer 5

Medications and stress can make you sensitive to caffeine.

Answer 6

empty stomach?  Too many cups of coffee.  

Answer 7

Every time you drink tea, coffee, cocoa,  chocolate, or cola you are giving your body a 'hit' of caffeine. Along with nicotine and alcohol, caffeine is one  of the three most widely used mood -affecting drugs in the world.

Caffeine stimulates the cortex of your brain heightening the intensity of mental activity. This can result in a temporary feeling of alertness and, in the short term, banishes drowsiness and feelings of fatigue. In those who already have high levels of anxiety the heightened intensity of mental activity can produce unpleasant effects, such as the ones you describe.

As with any drug, you may react differently each time you use it. You may have perhaps increased the caffeine intake by drinking more cups of coffee, or using a stronger blend.

The richest sources of caffeine are tea, coffee, cola drinks, some over-the-counter medications, chocolate, and cocoa.

As little as 20 mgs of caffeine can produce noticeable body and mood changes.

An average cup of tea contains around 50 mgs of caffeine, an average cup of instant coffee contains around 70-100 mgs.  

Filter coffee (called 'drip' in the US) can contain 25-50% more caffeine than instant.

A 340 ml or 12 oz can of regular or diet cola contains between 35 and 45 mgs. of caffeine depending on the brand  One ounce (28 grams) of chocolate contains about 10-15 mgs .

(An average cup is about 6 UK fluid ounces or 170 ml. Your precise intake of caffeine will, of course, vary with the strength of the drink. One person's mug of instant coffee might have 75 mgs while another person might prepare a 200 mgs hit!
