I am drinking Tetley green tea from one month back and now my metabolism of my body gets very good. I was very depressed from laziness one day of my friend suggested me to drink green and tea its very healthy and it will help to do more focus on your work and I started drinking this brand of Tetley green tea and I realised in very 2nd days I felt very focused and energetic. I got more weight than BMD approx 4 kg but when I started drinking green tea from last one month I reduced my weight 2 kg. Its very healthy.
