here's a link to a site about coffee addiction and the negative
health problems associated with coffee drinking....
i was once taking gurana a south american herb
for a boost in the morning along with a cup of
coffee at home and a large dunkin doughnuts ice coffee
before i started work . Not knowing that gurana is so loaded with
caffiene ....i was totally over amping
...my brain was about to explode!
