Cant keep anything down not even water im worried im going to be dehydrated

Don’t let it go on too long . I waited 3 days and was seriously out of it. By the time I got to the hospital they were shocked I wasn’t in a coma . My sugar was so low from not being able to eat or drink anything . I couldn’t even walk into the hospital. They had to pump me with so much sugar and water before I started to feel better

Try sucking on ice or a popsicle that’s what I had to do
