time zone work problems

Lately, the husband has trouble in sleeping. With him being assigned with Asia market, while his head office in West Coast ... coordination correspondences really hard. And with his line of work now, he's almost 24/7 online with the global time difference. Thus, his sleeping patterns already eratic. It took him months to adjust with this kind of time zone work differences. Thanks to sleep aids he was able to cope and have a good rest. He's usually sleep most of the morning, and wide-awake by night time. Time differences no more. He can deal both worlds in his own time ...and still get enough rest =)
