Several days ago, I came down with a hacking cough, a little fever, ect....I went to my druggist and asked what can I take..he said, Robitussin-Dm so I bought the Night-time, too....Due, to my Russian grandchildren coming home..Wanted to be able to take a quick peek at them Started this 3-4 days ago... Maybe I was nervous about seeing them..but, have not had an appetite..for several days.(probably the yucky cold meds too).....I thought before I take my coumadin tonight..I had better check my INR..Can you believe this..Hit a perfect 3.0 ..Last week I was 2.9....So, maybe anyone with a cold can remember..this is a good OTC med to take....Cough is better..but really running nose, eyes, ect. No fever..Guess it will have have to run it course. Bonnie
