You may have the same bug that my wife has been dealing with for the last two weeks. She actually went to the doctor, got put on some prescribed medication and still can't shake it. Some of her symtoms are sore throat and continuous coughing.
I have been so busy with work that I have only logged 50 miles for last week
That is totally messing with me because I am used to logging at least 125 per week even on a bad week.
I hope you start feeling better, soon.
