Morning sickness for twins

Hi mommies, I’m at week 12 of my pregnancy and my morning sickness hasn’t gone away. I’m unable to keep much food and drinks down and have lost 10kg in the past month. Went to KKH once and they gave me IV drip and anti nauseous jab (doesn’t really work). What else can I do to stop losing weight and eat more? 😭#advicepls #pleasehelp #pregnancy
