I've always been told that it takes one day per hour of time difference to recover from jet lag. So, it may be a while

I'm a huge believer in natural light. The quicker I can re-set my body clock to the sun, the better I do. (Get good and sleep-deprived to start, go to sleep as soon after sunset as possible, and let the sun wake me in the morning.) But I've never been farther than central Europe (five hours' different), and I'm lucky to live where I can allow natural light into my home without too much artificial light getting in at night.

Be extra careful during the transition, while your brain is fuzzy, especially after dark!

Good luck with the skirt.
