i am trying airborne, since i noticed that i was getting sick right away. has a few of the same ingredients as Yin Qiao, and the zinc that cold-eeze has...figured i might as well try it 'cause most cold medicine doesn't do much for me. the anti-inflammatory part i particularly like... so far, either i'm not that sick yet, or it's working, because i don't have most of the symptoms. i'm just tired and disconnected and not in top mental shape to write a paper. but i took a nap and drank some tea and feel much better than i did before.
