Tare, did you get the flu shot? (I know it is not perfect, but it is supposed to have some benefits).
I've actually only had the shot once, and that year I got the sickest I have ever been. High feaver, vomiting, whole 9 yards. Never had it again.
I did find my health correlates to exercise. All I had to do is exercise hard about once per week and no problems. Been doing that ever since. Actually it may correlate to stress since the only reason I wouldn't exercise was some pretty severe external pressure - most of these I have been able to avoid recently.
Well, hope you feel better.
