I Have A Question On The Closemyer Slimming Green Tea.

I have a question on the Closemyer slimming green tea. It has got great ingredients, and it really has been making me feel great. I have been having it for about a week or 2 now, and still having it twice a day. My tummy runs everyday but it doesnt hurt. I would just like to know something... I read that the long term use of slimming green tea can cause chronic constipation? is this true? I do not want that to happen to me
