Ah, good recommendation ng OB mo! Oo, a few of us moms have tried Wilkins Zero or similar carbonated water brands during pregnancy, and it really does help with the nausea, yung bubbles talaga, nakaka-settle ng stomach. Just make sure you're drinking enough regular water pa rin throughout the day so you don't get too much gas, kasi sometimes the carbonation can make you bloated if that's all you're drinking, pero okay naman siya overall especially kung ito ang nag-help sa nausea mo!
