butter i heard that it is better to stop...if not reduce ur caffine intake... i read in some recent medical articles, too much caffine (tea, coffee, coke) will cause miscarriages... and the article also advice that if a woman wants the fertilize egg to implant into the womb, it's best not to take too much caffine... cos sometimes, too much caffine intake, the fertilized egg cannot implant... so i think slowly reduce coffee,tea & coke...
