Go for the nasal spray if that makes you more comfortable. Mrs S travels so much, she is a virtual petrie dish for bringing home bugs...she may need it more than you do! I still say, if you eat healthfully and avoid shaking hands and being around sick folks, you are gonna be fine.
That is excellent advice! Thank you! I didn’t even put the two together. She would be the one to give it to me...or the house keepers I always worry about because they come to work no matter how much they are coughing and sniveling.
