Paul,
I'd not worry about getting sick. If you do get to not feeling good, I'd
avoid going to the doc anyway. I'm serious when I say that each time we
head to the doctor for meds, we become less immune to fighting them off
with that med. My brother had this with penicillin, my wife no longer can
take sulfa drugs or penicillin due to allergies to it now, and it is proven
to create stronger strains of sickness as people use meds every time they
get sick. Hopefully your current ill feeling is as you say. If we hear a
great rumble from the Carolinas, we will know you are doing better.
Brad
