I'm a pretty big medicine person. I don't like admitting this, but when I have a headache, I'll take a Tylenol (or Excedrin - if it's really bad). When I have a cold, I run the gammit of taking Cold-eeze, Emergen-C, DayQuill, Zinc, etc. My dad always tells me to take Zinc. Point being, I get sick, and I rush to the pharmacy. At my chiropractic appointment yesterday (which I tried to get out of saying I was sick but was told to come in anyways because it would help me get better) my doctor told me that all I needed was the adjustment to boost my immune system. She said to just let the cold run its course, and to stop taking medicine. I'm still waiting for that treatment to work.
