It's not abnormal to get sick when you enter a new environment.  New job, new living quarters.   I have not had a summer cold in 20+ years.  There is actually what I consider to be close to a cure for the common cold

May I recommend Zicam?  Zinc in itself, is pretty effective for colds.  The downside, it's kind of hard on the system.  In fact, It's upsetting my stomach right now.  My throat is much better though.
