You can take tums or mylanta (preferably sodium free). Hope this helps.
I currently take Zantac and its perfectly safe. U could get it over the counter but if u get it by prescription then u can get the stronger dose of 150 mg twice a day. It has been my god send as I was suffering with everything even drinking just water. I'm currenty 15 wks and have been taking it from the beginning. Good Luck my dear :)
I love tums smoothies flavor keeps the morning sickness and heart burn away :-)
