I used to to do one or two trips a month to the States, usually three to four days but sometimes it was one or two then straight back to the UK.
I used to stay up as late as I could when I arrived & then power through the next few days, if I was only there for a short time that worked well & I would sleep on the way back, I usually flew in business or first class so could stretch out.
Thankfully those days are in the past & trips to the States now are generally for holidays, the last few times we have gone over we have used the same strategy which is snooze for a couple of hours on the way over, unpack when we get to the hotel then head out for a quick bite to eat & some drinks, we can normally keep going till midnight then crash, we do find ourselves struggling by about 10pm on the first couple of days but after that we are fine.
We don't have kids, so we fly in business class which does make a huge difference particularly on the way back, we crash out straight after dinner & that's us until they serve breakfast.
The first day back is usually not great but we are usually over it by day two.
Each person is different, avoid excess alcohol especially on the way back, a couple of drinks are fine but the worst thing you can do is drink your way over the atlantic on the way back, I've done it a few time when I was younger & although it's great fun at the time when the hangover & jetlag kick in together it's the worst feeling in the world wherever you happen to be sitting in the plane.
