i was drinking the lacid stuff and i was still having bad attacks with my gas and bloating..and i read up on heathers sheet and it said something about casien and whey and it had it in there,and it still said milk just not the lactose in it.i switched to soy milk that helped a little bit but i still cant drink it,it stills gives me bloating bad!so i use the rice dream and do relley well on that.
