Open Question: Thowing up multiple times. What to eat and drink?

Since yesterday mid morning ive felt horrible. I went to bed for the rest of the day and had little to eat. I ended up throwing up 3-4 times in a row (within a minute) and all night i had diarrhea which was yellow and liquid. This morning i took some stuff to help my stomach and diarrhea and ate an apple and whole grain water crackers, but i threw up again and kept throwing up until nothing
