Hi Brian. Are you eating? If so what are you eating? Are you keeping food down?
Green tea is good, as is fresh carrot juice if you can get some at a health store. Light vegie soups are good. Vita C powder. Drink water and herbal teas, like peppermint, catnip, camomile, etc. If you live in a city and have a large health food center, often folks in the center can make recommendations based on what they've learned from customers, etc. Avoid pastries, milk products, meats except for maybe some broiled fish. Once you begin to recoup, brown rice is good with steamed vegies. If you eat, eat light and drink a lot. Get plenty of bed rest.
DISCLAIMER: Consult your doctor, preferably a doctor who utilizes alternative wholistic treatments. They treat the body, not the symptoms. Most healt stores know who these are or you can search google for your area. The above is suggestions of things we do which work quite well for us. We use no antibiotics or drugs due to side effects and problems with them, but that's us and not to be construed to mean we are claiming to have a cure.
We seldom ever get the flu. We try to eat natural foods void of white flour, white suger, etc so as to pevent disease. I will remember you in my prayers. God bless.
