You need to star looking at why. What are your risk factors for getting theses colds? Do you smoke? What diseases do you have that might predispose you to getting colds? (diabetes, Asthma). What kind of life style do you live?(sedentary). What medications are you on that might inhibit your immune system? (steroids). With the answers to these questions you will be better equipped to figure out why you might get so many colds. Oh and another big factor is ; do you have any small children going to daycare?

This may seem like a silly question, but after you get over each cold are you changing your toothbrush? Everytime you get sick, once you are over it, you should dispose of your old tooth brush and begin using a new one.

i boil my toothbrush in water. I found out that my allergies were not allowing the virus to go away so I went on antibiotics and it got rid of it. thanks for your help!
