I am nauseous, some cramping, loss of appetite,exhausted, period was only for one day, not pregnant, I woke up at 3Am Friday morning with diarrhea and severe cramping and abdominal pain, I have not had a bowel movement since then. Since that morning I have been nauseous everyday and when I think about food I feel nauseous. I will eat once a day or not at all and then when I get hungry I eat a lot and then begin to feel sick again for the rest of the day. I have begun only eating about once a day and I stopped snacking because I feel sick. I am very tired all the time, especially after work when I wasn't before all of this. I just feel sick all the time.
