Eating food is a no go....

For the past three days any food I look at, smell,  think about, or talk about makes me want to vomit... I can eat fruit and raw veggies but after I'm done I feel sick.... 8 would munch on crackers here and there and today I upgraded to cheese and crackers but I still can't eat regular stuff!!! Ladies have you had this problem? And what have you done to help Im hoping this doesn't last for too long.... my poor husband has almost all of my symptoms 😷🤕😢
