Preparation of cold and flu toolboxes are strongly recommended. You do not want to sick and realize that you are out of the basic supplies. Going to the drug store when you are sick and fatigued is not good for you nor the other people in the store.
The following items should be in your Cold/Flu Toolbox:
Boxes of non fragrant tissues
Tylenol or Motrin fevers and body aches
A functional thermometer
Throat lozenges
Vitamin C to boost your immune system
Vitamin D
Over the counter cold medicines ( if approved by your doctor).
Ginger ale, soothing teas, and your favorite sick role comfort foods.
I hope that you do not need to use this toolbox frequently this year but it is always best to be prepared.
