Coughing Home Remedy

I've had a cough for a little over a week now. When I got home for my dad's birthday/Christmas, my mom told me about a way to quell my cough when I was about to go to bed (seems like my symptoms get worse around bedtime). You rub Vick's VapoRub on your feet, then put on socks to keep that stuff from getting everywhere and wearing off. Sounds like a crazy idea, but I was in the middle of a fit and ready to try anything. Miraculously my coughing was attenuated. I didn't completely quit, but they were less harsh and longer in between. I'd recommend giving this a try.
