A red cross country red eye is not jet lag.
It's called EndAlert and it is for what it says, being alert, but I never heard of NoDoz or Coffee helping jet lag, it only masks it for a while. That's why I use the homeopathic No Jet Lag mentioned above, it works well and they have science http://www.nojetlag.com/jetlag5.html
also pharmacist speaks highly of it.
