Water makes me sick

Anybody else throw up shortly after drinking water? I drink cold water and vomit within 5 mins whatever I had just eaten along with the water I had just drank. I'm only, roughly, 7w3d and only started throwing up a few days ago. Then I'm nauseous throughout the whole day. Is there any way to ease the constant nausea? Also what can I do about the water situation?? Any suggestions is highly appreciated. Thank you 🙂
