What is your Zantac dosing? How much and how often? Have you noticed it wearing off before the next dose? How do you know if it's wearing off? Ours is 1.5 mLs twice a day or 1.0 mLs three times a day. I've tried both options but they seem to not last the whole day with either option. I think I've managed to time two doses such that they wear off during the night since DD sleeps 8-9 hours each night and by then most of the formula is out of her stomach anyway...
