#1. Go to the Dr.
#2. If it is a productive cough (phlem) you don't want it to stop. Take an expectorant like mucinex. You want to get rid of all that garbage in your lungs. DO NOT SWALLOW IT! Spit it all out.
You need moist heat, boil water, get a humidifier etc...
#3. If it's a dry cough then you need a cough suppressant like Vicks niquel etc...
#4. DO NOT MIX MEDICATIONS!
#5. Drink more water than you think you need. When you take medications they may numb your senses to your illness but also numb your ability to know thirst. So DRINK UP!
(lay off the sports drinks and novlty drinks..water is best)
#6. Real, home made, chicken soup actually works. (no joke)
#7. One a day multi vitamins--take one in the morning and one after lunch.
#8. >#9. ># 10. ANTIBIOTICS ARE A LAST RESORT FOR BIOLOGICAL PHENUMONIA NOT FOR FLU!!!
FLU is a virus...antibiotics WILL DO NOTHING FOR IT!!!
If you follow the above, in about 5 to 7 days you should feel a little better.
The cough won't go away completely for several weeks though. It takes a long time to get rid of the crud that's building up in your lungs right now. I know that's not what you want to hear but at least you know what to expect.
