Useful when travelling overseas

I bought the spray on a pretty good discount to test out initially. The spray has a mint flavour which isn't too strong, but does taste a bit artificial. In addition, the packaging recommends between 1-10 sprays. I used this on several longer flights to help sleep and minimize jet lag (~5 sprays) and found that typically, sleeping was easier than usual. It is difficult to tell if it's placebo, however, it has been effective thus far. I will continue buying it when there are decent sales.
