Ay, that queasy feeling na hindi lumalabas is the worst talaga! What I do when I'm in that boat is sip on something cold like water or ginger ale slowly, eat small crackers or toast, at I try to lie down para calm my stomach, a few of us mums swear na lying flat on your left side helps. Sometimes fresh air or opening a window din, or even just distracting myself with something light on TV helps take my mind off it. But if it's been going on for a while or you're feeling really off, better check with your doctor para sure kung may underlying cause talaga.
