Just got myself put on drip for a while yesterday because of the hyperemesis again. Generally not too keen on the taste of water (husband is puzzled why there's a taste to water) so I can hardly bring myself to drink plain water. So far what works is hot Milo and I'm not adding milk or sugar to it. We have a can of Milo Gao Kosong and I just mix a few spoons of this with hot water and keep it in my thermal bottle and have it every few minutes or so at night. Not the healthiest or best choice but I'll take whatever I can keep in my stomach and not get turned off. And bread. These two are what my stomach doesn't reject and I'm glad I can still eat something somehow.
Hope the rest of you who's going through the same are staying strong and keeping well. :)
