Highly Effective Product
I've used NZ Natural Formulas Anti Jet Lag on several longhaul flights, to North America, Europe and eastern Russia. I would recommend this product to anyone contemplating doing any flight of several hours. I take it as recommended, before, during and after the flight, and have never had to cope with the jetlag that I've seen others struck with. Sometimes I've felt tired after a flight, have used the spray and had instant relief.
