So on top of the surgery recovery, I'm starting to get a little mucusy in the back of my throat and while I'm not sick now, signs like that usually mean a cold is imminent. Now, I'm going on a transatlantic flight next week, at the end of which I will be reunited with my boyfriend who I haven't seen in almost four months, so I CANNOT be sick right now, full stop. Any tips or suggestions on how I can head this off before it really gets going?
