May I suggest Airborne, or one of its less expensive knock-offs? (G picked up some Wal-borne at Walgreens for me yesterday, he said he had thought it was about $6). You are supposed to take it at the first sign of a cold as a preventive measure. Reviews of it conflict, though many swear by it. I could not tell you since I started taking after the cold was in full swing, but I certainly don't think it could hurt.
