Headaches in the Morning

I feel quite sick this morning.  I have headaches and then found out my wife and son also have the same symptoms.  I suspected the Chinese tea as I just finished drinking it.   So did my wife.  But B1 pointed out he did not drink the tea.   It could be the weather i.e. the temperature as well as the pressure.  I feel the malaise and nausea.  So my lunch is canned sweet peanut soup.  After the sweet high cal lunch, I felt much better.  But it because a nagging headache that last until now.  I am not debilitated, it is just not feel chirpy at all.
