I have been under the weather since just before Labor Day weekend - so over a month now. It started out with what I assumed was seasonal allergies/summer cold with extreme coughing and congestion. After weeks of coughing and feeling rough, I am now feeling even more run down no matter how much a sleep in a night. No energy, light-headed/feeling faint at times like today, major headaches bordering on migraines, upset stomach with vomitting, etc.
