I got bali belly about a week ago or so, before i left i was given some gastro-stop in aust by the doctor, i hit that over there on the first signs of bali belly, but with little effect. In search of relief i found googled and consequentially bought some entro-stop, for about 6000 Rp. This was the best thing i have ever done. At first i only dared eat and drink in small quantities, however i slowly increased meal size and liquid intake and within 24 hours i felt 90%. i suffered the occasionally stomach cramp afterward but to a much less extent and only had to take 3 tablets in total.
Well worth the purchase, i would recommend these to anyone. ;)
