I used to drink quite heavily. Felt groggy the next day and put on a lot of weight. six months ago I substituted a cup of coffee for each cocktail I used to drink.
I feel better, have lost about 24 pounds and have much more energy. I drink 4-6 cups a day and have no problem sleeping.

My husband was diagnosed with Parkinson’s disease nearly 7 years ago, when he was 49. He had a stooped posture, tremors, right arm does not move and also has a pulsating feeling in his body. He was placed on Sinemet for 8 months and then Sifrol was introduced which replaced the Sinemet. During this time span he was also diagnosed with dementia. He started having hallucinations, and lost touch with reality.I searched for alternative treatments and and started him on Parkinson’s herbal formula i ordered from Health Herbal Clinic, Just 7 weeks into the Herbal formula treatment he had great improvements with his slurred speech, there is no case of Rigid muscles and Slowed movement (bradykinesia) since treatment, visit Health Herbal Clinic official website www. healthherbalclinic. net or email info@ healthherbalclinic. net. This treatment is incredible!

Great article. But the Asians have solved this quandary for us. Drink tea. They have been doing this for longer than time itself and the health benefits are never disputed. Plus, recently there has been too many scientific flip-flops like this. I don’t trust any product that was once on a cancer list and now is on a healthy list! I for one won’t change my habits and will designate coffee as a possible carcinogenic. Please also check to make sure the study was not funded by Starbucks.

The study was funded by research grants with no connection to the coffee industry. (And coffee was never truly on the “cancer list” – a single study suggesting a cancer connection was compellingly discounted given its flawed statistical methods).

People who are caffeine sensitive should consider taking this article more lightly; the rise in coffee houses would like us to think coffee is not a ‘drug’, but for some like myself coffee isn’t good. Just one cup in the morning and I get heart palpitations when I try to sleep at night, also I have noticed it tends to make any PMT symptoms such as sore breasts worse. Much as I love a coffee, if I am out I have to view coffee as a ‘treat’, here in the UK I ask for ‘one shot’, this usually helps.

One side effect of drinking a few cups of coffee a day is that if you are quenching your thirst with coffee, and urinating frequently, you may not be drinking enough other liquids to hydrate yourself. This can contribute to kidney stones (I had one). Now I try to drink a cup of water for each cup of coffee I drink in a day.

I switched from coffee to green tea last year and love it! Hot green tea in the morning and ice down the remaining(including the 5 tea bags) in a 52 oz travel mug.
