Having medical experience..I was always told that drinking water is fine unless you are naucious..If you are naucious..you shouldn't drink water as that will only encourage the ill results..Eating chipped ice however works..Jello and dry toast..Avoid the greasy food.
rt49 - talk about yogurt - a friend of mine has been eating one container of yogurt everyday for years - never missing a day and has not had a cold ever since! When I was doing it - I never got a cold - I stopped about 3 months ago and I got a horrid summer cold in August that turned bronchial on me and I am still not back to normal (whatever that is - LOL). Time to get back to the yogurt routine!
Hubby takes yogurt with his lunch everyday for work. He's rarely sick either, but he has hayfever. Unbelievably, since he's started taking yogurt to work, he's actually cut down on his sinus/allergy pills. Which is nice, it saves us some money, plus there's that whole thing with a person only being able to buy a certain number of packages of allergy medication containing ephedrine.
