My husband had a stomach ache in the middle of the night and after taking pepto bismol felt better. Today while at work he said he felt fine but after getting home and eating supper, he started having bad stomach pains, nausea and finally vomited. For the last three hours he s been feeling worse, complaining of severe stomach pain. Has tried taking pepto bismol, and an antacid, just in case, but nothing seems to help.
