Hi, i weigh 125 , 5 3, female age 21. Iv always been a heavy eater i have about 3-4 meals a day including snacks. But in the last week or two iv been feeling dizzy, nauseous, really bad headaches. Iv been noticing that i get really strong cravings to the point where im litrally drooling and after i eat i feel gross and like puking, i get really hot and tired. I cant even smell certain things because i automatically get nauseous. I dont know whats wrong, please help?
