Aiya, afternoon sickness is real lah, a few of us mums kena this too, not just morning! Since you're only 6 weeks, your body is still adjusting to all the hormones, so it should settle down after the first trimester. Try eating small snacks before balik kerja and stay hydrated throughout the day, sometimes it helps if you makan something light in the car on the way home. But if the muntah gets worse or you're struggling to keep anything down, best to check with your doctor just to make sure everything is okay, ya? Moga it passes soon, mama!
