I am a 20 year old female who finds myself sick constantly. I get colds, and other illnesses more than any person I have ever known. This past winter I got pneumonia twice and bronchitis twice. I never have a day where I wake up in the morning and actually feel "good". I take vitamins, and recieve b12 shots every 10 weeks from my doctor, but yet my immune system still can't fit the simplest of colds off. I don't know what to do anymore because it has begun to seriously affect my work life. I eat healthy, and do what I can for excercise, my only down side is that I am a smoker. I am not sure what else to do and have thought about asking my doctor to run several diagnostic tests to see if she can find the cause of my problems, but I was wondering if there was anything else I could do before that to help stop the problem in it's tracks....
any advice would be greatly appreciated!
