I've been using Airborne for about 4 years now.  Its great to take before going anywhere where there is going to be a large crowd with sick people.

I also use it at the first sign of a cold or any illness and every time my illness lasts days less than any other family member that doesn't take Airborne.

There are many flavors but I like the lemon lime the best.  To drink it quickly I put a tablet in a glass of cold water but if I already feel ill and want something hot and soothing for my throat, I mix one with hot water.

The only thing I did not realize until I seen it on television from a doctor...
