My dad is coming over today. He lives the other side of the world. I've not seen him for 5yrs, dd was a toddler, ds was in nappies. I've got the worst stinking cold. Had it a week and a half and now descended into full on snot. Any tips to help me find some energy, be less snotty, help it naff the hell off, and prevent contaminating my dad?! Is there a miracle cure I somehow don't know about!!
