Aw hirap talaga yun, mama! A few of us here went through that too, one of my mum friends swore na frequent small meals instead of three big ones helped her, plus staying hydrated really made a difference kaya try mo yung approach na yan. Ginger tea or even just smelling lemon sometimes works din, pero honestly if it's getting worse or you're not keeping anything down, best to check with your OB para ma-rule out if may underlying thing at ma-suggest ng proper remedy, don't tough it out lang, okay? Hugs, I know how draining yun!
