Wa'alaikum salam! Honestly I haven't tried sea band sendiri, but a few of my mum friends swear by it during their first trimester, one of them said it worked better than she expected, especially for the nausea part. The thing is, morning sickness ni varies from person to person, so what works for one orang might not for another, tapi since it's non-invasive and harmless, boleh je try. Ada juga yang combine it with small frequent meals dan plenty of water, so maybe that helps too? Worth giving it a shot if you're desperate for relief!
