As I am in Prague for the majority of my year, jet lag is sleeping for 14 - 16 hours after arriving in Prague. When I get to Sydney, it is sleeping in the middle of the day (I usually arrive on the morning flights), being up at 8 pm. Awake for the next 24 hrs, then nanna nap at 5:30 pm then being up till about 2 am for the next 2 weeks. (As I am normally arriving in July, all I can say is Vive Le Tour !!!)
I have read that jet lag is worse when going from west to east, hence why people normally have it affect them less in Europe, and that normally it takes about one day per time zone crossed to get over it, but I am sure it is different for everyone. Last year, I did do two one night stopovers on my way to Sydney, I didn't find it helped at all.
Cures to avoid jet lag I have read about (not sure which ones work):
- Arrive at your destination on an evening flight
- When you are on the plane you should be in the time zone of your destination (eg. sleep when its night in your destination, etc.)
- Drink a vitamin water drink before you get on your flight to replenish electrolytes (stop dehydration), and avoid coffee and alcohol
