I chose to disagree with respect.
What I quote are renowned, respectable journals. There are none more respected that New Scientist.
What you describe is someone who takes Anti Depressants too !!!
Any artificial chemical introduced to our bodies by the medical profession (or ourselves from over the counter) for normal daily life will upset significantly chemical balance. As will Coffee.
BUT what percentage of the world population drinks Coffee
?
If you read the articles, over consumption of anything is not good. But statistically Coffee is a normal antidepressant if you are not taking anything else.
These articles came from a doctor friend. Don't take chemicals.
Once when I was very young I was prescribed anti depressants and I had a few pints of beer. Since then I wont take any prescription drug unless I am really ill and I wont touch anti depressants.
Have a Coffee and I mean ground beans.
Life is good, once you understand.
We make our own happiness and everyone likes to be with happy people.
One man's junk is another's treasure and life goes on. Make yourself into a happy treasure. :-)
