Uy, yan talaga ang struggle ng third trimester, a few of us moms dealt with the same thing, super annoying lalo na kapag tulog na! Try eating smaller meals throughout the day instead ng malalaking meals, at avoid spicy or fatty foods muna; a lot of my mom friends swear by sleeping with extra pillows para ang upper body mo ay elevated habang natutulog, sobrang tumutulong talaga. Definitely mention it sa OB mo next visit though, kasi may safe antacids na pwedeng i-recommend niya para sa pregnant moms, at importante na i-address para makakuha ka ng mahusay na tulog pa rin before baby arrives! Kaya mo yan, first-time mama, this part is rough pero temporary lang once you deliver.
