It hit me hard today, I woke up coughing which turned Into dry heaving, crazy excess salvia. I am too nauseous to eat. I try to drink a lot of water or ginger ale. Also had such a bad headache I gave in to a warm bath and an advil. Other than being tired since week 4 I haven't felt anything thing until now, also adding some cramping. This is our first. Is this normal? Exhausted, hungry, & tired. :(
