Vicks is the thing ! It has been around a very long time; I posted the other day that a couple of years ago I was the most sick I've ever been with a cold...according to dr. it wasn't the flu...just a cold. Put Vicks on the bottom of my feet, white socks, Vicks on my chest covered with a t shirt and then pj's.....condition improved greatly !
Do whatever makes you feel better and GO to retreat ! Once you get there you'll feel better I'm sure ! Have a great time.
