Knocked out by virus

Sorry to hear you sounding so ill. I've always taken high dose vitamin C and on the recommendation of a nurse, made sure it included zinc. Lately, with a sluggish immune system, I also take elderberry cordial either as my own brew or as Sambucca. Echinacea has fans amongst some, I'm not sure about it. Some people swear by a nasal medication which I think is called First Defence. Lastly, despite being veggie most of my life, I do think the old remedy of chicken soup helps - I think there is some sound, scientific reason why this might be so.
Hope that helps.

Liquids and rest is the best medicine! Hope you feel better soon. I take Echinacea when I feel a bug coming on and usually crave orange juice perhaps for the extra vitamin c.

You must find ways to strengthen your immune system. Look for supplements that contain omega-3 fatty acids and antioxidants.

Yousound as if you have made an excellent and rapid recovery fizzers ?
It is an idea not to do too much after a viral infection though to let your system get back to normal.
If you have shaken this off in under a week, I think your immune system sounds just fine - quite enviable in fact.
