Suggest Treatment For Influenza And Cough

I had influenza (not stomach flu) about Jan 6...still coughing a bit...not back to normal food amounts-which isn't a bad thing...but my one bowel movement a day is soft loose stool...my hubby also had the same flu and went through this...I am assuming its just a side affect of the virus...anything I can do to get back to normal. I use a w/chair so I like being regular and know my patterns
