My husband has been ill for almost 3 weeks..the first week was coughing, mucus, no fever, body aches. the 2nd week added vomiting, not able to get out of bed, no fever. it is worse in the morning and at night. he has taken Dayquil and Nyquil and nothing is helping. in the morning and night, he feels very nauseas. it has been over 12 hours since he last vomited but this morning, he was very nauseas. loose stool. yesterday was half loose. ideas?
