You’ll need a trip to hospital for iv fluids if it continues
If your not keeping anything down you’ll need iv fluids and anti sickness
I completely agree with the need for IV fluids and meds (Xonvea worked best for me) and also thiamine. At my worst the only fluids that stayed in a bit better was coke. Anything is better than nothing. Water is often tricky… a doctor friend advised me to just hold liquid in mouth as it goes in through skin too. We’re sort of sponges. It helped me a bit at times.
