I am the same. the return journey home is the one i am really affected by jet-lag. It could be because i know i am on more of a holiday and can relax. I have heard it said it takes one day for each time zone you pass through, but it could also be you know that you can take a break from the challenges of China.

I get jetlagged when flying from west to east. The other way doesn't bother me...that much, can be compensated with coffee. 

Definitely when going home, UK. It usually takes me about three or four nights of going to bed by 9.30-10 to catch up and get back in sync. Coming back to China doesn't really affect me.

for me is heavy when i come to china. flying home is no problem for me, probably because i m excited

I'm a night owl. When I come to China, I'm 12 hours difference. If I'm tired during the day I just push through it. I'm out later than I would be at home and I don't sleep long. It takes me awhile before I can get 6 to 8 hours sleep. When I go home, I can't get enough sleep for a couple of weeks.

I am prone to airportitus. It starts the day before flying where I usually can not sleep. I reach the airport terminal and I'm already a Zombie. Mostly I don't sleep on the more than 12 hours on the plane (just nod off during the movies). Then there is the stopover - will i catch the next flight to my destination? I eventually get back home or back to china looking and feeling like a dirty dish rag. After being scraped off the arrival lounge floor and taken home. So call it jet lag or call it a near death experience - it'll usually takes a week or 2 to scrape myself off the floor and resemble a human again.    

I never really experienced jetlags, after i arrive anywhere i just go straight to drinking haha

Coming back to the US is always awful in terms of jet lag.  I've been back almost 2 weeks and I'm still not quite right.  About the time I get right, it will be time to go back to China.

Someone mentioned looking fresh in airports. If you've got a long layover in a decent airport, you can spring for a one-day pass at one of the airlines' lounges. Usually they will have shower facilities. I actually started scheduling a nice 5 hour layover in LA instead of a taking a direct flight home. Gives me a chance to feel human again before arriving home.

Never been jet-lagged coming or going. I don't understand the concept.
