The kids have had a runny nose, slight cough for quite awhile. This Sat I got some postnasal drip, which is giving me a ticklish cough and sore throat. In addition, I feel like I'm trying to cough up something, little gobs of mucous (TMI) come up when I cough. That's the main part that's bothering me b/c my throat is a bit sore and I keep coughing.

Should I get some mucinex? I want to stay away from anything I don't really need b/c I'm nursing. Any suggestions?
