I woke up this morning with a pretty bad head cold and painful sinus.I managed to run about 3 1/2 miles the air was very heavy and humid.There is an old wives or grandmothers remedy that id you drink sweet black coffee it will help a sinus problem,so I did and it helped a lot.I still need to deal with the fact that I have a cold ,but it is at least better for now.I am not a doctor and I do not play one on TV,so judge for your self.
