Caffeine stimulates the nervous and cardiovascular systems.

Caffeine also increased the heart rate, blood flow, respiratory rate and metabolic rate for several hours.
If caffeine is taken at the night time it may interfere with getting to sleep, it will keep you awake.

The effects of caffeine are not same for each person; they depend on many other factors also.
If daily caffeine is taken more than 600 milligrams, that is six cups of coffee daily;
caffeine can cause nervousness, sweating, tenseness, upset stomach, anxiety and insomnia.
In few persons it can even prevent clear thinking and increase the side effects of few medications.

I really like coffee but none of that instant kind - if I'm going to drink it, I want a strong French dark roast or Sumatra or something like that. I do like it with milk or cream, or a latte, without foam. I can drink it cold, no problem. Three cups a day works for me but I don't mind more. I also enjoy tea, black tea, like the darjeeling and assam from your country and, of course, that wonderful chai but I also like green tea and some of the wonderful herbal teas that are on the market now. My friends from England tease me that I don't make a proper cup of tea. I think they're still made about the Boston Tea Party.

RNSANE June 27, 2010  

that's mad, not made

sm,  June 28, 2010  

I like all types of tea.
and coffee.
In past I thought about writing on the Boston tea party.

sm June 29, 2010
