Are you feeling OK ?   My stomach is bothering me .   What have you been eating ?   I had a ham sandwich with mayonnaise for lunch .   Maybe the food had something wrong with it .   It could be bad food , but I didn ’ t feel so well yesterday , either .   Have you been under a lot of pressure lately ?   I haven ’ t been under any more stress than usual .   Perhaps you have caught that bug that is going around .   I feel like maybe I am coming down with the flu .
