On monday night my stomach began hurting quite a bit before bed, and when I woke up on tuesday I threw up every 40 minutes, but nothing was really there. I felt fine after a few hours, and just then this morning (thursday) I woke up and felt nauseous again! It kept coming in waves, and then tonight it feels really bad again! What is going on with me?? Also, does anyone know any home remedies for nausea?
