dyingg

Im not pregnant but I know majority of people read the pregnancy posts only so that is the reason im posting here (sOrry) sunday night in matter of 2 hours i mixed every kind of food up.Ice cream,fried food,grilled cheese,crackers and probably more that i cnt even remember.I usally eat very light and dont mix random stuff but idk what was wrong wth me that day.few hours later i started throwing up like crazy all night I could not even hold water down,one sip and i threw up like a waterwall.Next following days i threw up once or twice a day but today is friday and im still nauseous everything i eat makes me wana puke,i cnt hold anything down,im constantly wanting to throw up this feeling is horrible.I figured its food poisoning but then it would not last this long.Help what can i do to make it go away
