I am pretty good with jetlags either way, but there is 13-hours difference between Sydney and Halifax.

>Mmmmm, close to a day so probably not much change. I'm not sure that it's not the West->East that buggers you or t'other way.

>>>When I went to HK years ago, I've no idea HOW long I was travelling, as we had to change planes in the UAE, then Bangkok, and the clocks were continuously going forward. Got into HK in the evening and was so tired I was close to tears. But as I only had 5 nights there I couldn't get my head down - had to get out on the streets.

>>>>>I do have more problems going west, esspecially if the time difference is about 8 hours or more. Going to the west coast is always challenging. Getting back home (flying east) rarely is a problem: I can take a nap any time of day.

>>>>>I just came back from Washington DC on sunday and appart from getting awake in the middle of the night and needing a dooze during the day I'm fine. However I do remember my first and second time at the west coast. I was shaking just like I had a severe fever and could not sleep at night at all for the first three days.
