Hay, alam ko yan na yan talaga especially kapag first trimester pa lang, a few of us had the same experience, super frustrating talaga! Try eating small, frequent meals instead of three big ones, at drink water in between meals instead of during, kasi yun ang nakatulong sa amin. Some mums swear by eating crackers or ginger biscuits right after waking up, at cold foods sometimes help more than hot ones, pero honestly if it's really affecting you and you're losing weight or feeling dehydrated, best to check with your OB na para ma-monitor properly. Fingers crossed it gets better soon, mama!
