First of all, if you start to feel ill, give your body rest and time to heal itself instead of hoping it will go away while going about one's busy life. Often the start of a cold will just simply go away if you just take it easy a couple of days.

Second, all the general stuff about eating healthy, not smoking and staying in physical shape. If walking is difficult, what about swimming or cycling?

On stomach bugs there's usually one out of two culprits afoot: children or not good enough hand-washing. (stomach bugs spread by the fecal-oral route). Make sure to wash your hands or use hand-desinfectant before handling food. According to a friend of mine who's more often than not seriously immuno-suppressed to medications, being neurotic about this helps with reducing infections.

Last, you could try various natural remedies. Few have any real evidence, and I don't know much about it. But I've heard that garlic is supposed to enhance the immune system (AND it keeps nasty blood-sucking vampires away, which is a positive side effect)
An important thing if you start on some herbal medicines or other so-called alternative medicines is telling your doctor about it if you get any medications, since many of the herbal medicines interfere with drug metabolism in the body.



Hope you get well soon!
