The earth smiles in flowers

Feeling a bit wrung out today, after spending the last two nights awake with an annoying cough. Been told of an idea to ease this ??? vicks vapour rub spread on your feet, then putting a pair or socks over and sleeping in them. I'm debating trying this, anything to get some sleep. I'll let you know if it works !! Has anyone heard of this one ????One day left at work, because i have booked a few days off. Yipeee
