cold eze lozenges (similar to zicam, but imo tastier, and at least the last time I picked them up, cheaper) helped a TON when I had to get over the funk just before going in for surgery in january. I was also chugging down at least two packets of super-c (Emergen-C type thing) daily.

The same crud that co-workers were fighting for over a week, I kicked in about 4 days. I am a convert!
