Colds while breastfeeding

J

One of my disgusting coworkers came to work with a cold and has no decency when it comes to hygiene and keeping your germs to yourself, so I have come down with it too. Typically I would pop a bunch of vitamin d capsules and that has always done the trick within a few days, but I breastfeed and my son already gets a vitamin d supplement, so I don’t want to overload him. What are some other things I can take/try to help shake this?
