Aih, muntah-muntah memang sakitnya, especially when you're trying to sleep! Try ginger tea or mints, a few of us mums swear they help settle the stomach, and letak the pillow a bit higher so your head is elevated la, sebab kalau flat je memang lagi terasa nausea. Also minum air sikit-sikit je, jangan banyak, and avoid heavy or oily food for now. But if this keeps happening or you're actually vomiting a lot, better check with your doc cepat-cepat, okay? Bisa ada something yang perlu ditangani properly.
