On multiple occasions I’ve seen someone at CVS / Walgreens, coughing up the whole store, buying typical sickness stuff. We all get sick, so it’s a good idea to get these things before you need them. A few things you should have include:
soup
ginger ale
tissues
thermometer
NyQuil and DayQuil
hand sanitizer
aspirin
vitamin C tablets
puke bucket
toothbrush (always use a new toothbrush after getting sick)
