I worked for a company who had ties with China and the guys would bring real green tea and give it to us. I was drinking this green tea every afternoon and after about two weeks, I started have heart palpitations when driving home from work. I went to the doctor but he couldn’t find anything. So I realized the only thing different I had been doing was drinking the green tea. I stopped and no more palpitations. I will never drink green tea again.
You can drink decaf. It does so some amazing things to one who drinks a few cups a day. However if you are not interested in the benefits I can see where removal works.
Mine was just the opposite. I had to cut out virtually all caffeine. I had palpitations and even went to the ER for it. After $14,000 dollars in tests they came back to me and told me nothing was wrong and to stop drinking caffeine.
