Just got home and almost threw up in the living room, just about made it to the kitchen sink with a mouthful of vomit. It was like a clear/white liquid that tasted like stomach acid and there was quite a lot of it. When I had finished I drank some water and it tasted like sugar?! What on earth? I had an empty stomach when I was sick but now I have eaten I feel better. Should I be worried or does this event sound normal?
