So gang - maybe I should have seen a doctor...

I had a cold last week, but feel fine for the most part except for the periodic coughing gunk up from my chest. Am an asthmatic (EIA), but because my peak flows are down a bit, I've increased my daily does of meds. What I'm coughing up doesn't look to be infected (white to pale yellow, not green. OK, TMI, sorry), so I haven't called my doc. The MS Tour is tomorrow. Any suggesting on coping? Anything I should stuff in my pocket to deal with the periodic coughing fits?
