I am sneezing, coughing and congested. So are other members of my family including those who came home from Florida with me. I feel fine but am tired (probably a lack of sleep). They, however are just miserable and have additional symptoms that I thankfully am not sharing. Fever, chills, thick mucus, aches and a total lack of motivation (so they say). I think that my problems are due to allergies and they have a cold or the flu. If you are wondering about your symptoms here is a great link to About.com that will give you some help in sorting things out. Of course, a visit to the doctor may be in order for some and do not let the Internet be a substitute for good health care!
At my house, these young and healthy individuals should bounce back quickly but since Mom (that would be me) is taking care of them and they are on vacation this could take a while.
