I have some serious acid reflux happening tonight. I have already taken my famotidine. But it is taking to long to work. I can feel it in my throat even my water is making it worse. Same thing happened to me when I was sleeping last night my heart burn woke me up out of my sleep. I thought I was dreaming about having heart burn but I really was having it. This crazy my chest is burning.
