Acetaminophen

The active ingredient in pain killers such as Tylenol and Equate. Does this drug really help? I have heard that it simply masks your pain without actually fixing anything. Yet, I recently became violently ill and took several doses and started to feel better.

Is vitamin C a better option to boost your immune system? Perhaps something else? Or does acetaminophen actually help you fight off illness? This debate has been going on for a while.
