Still adjusting to the Qatar time schedule

Hello guys, sorry for not posting regularly. Just need some more discipline.

It has been 3 months in Doha already. However, I still have yet to adopt their time schedule. Huh? what do you mean? While for the locals and foreigners here, they work in the morning, nap in the afternoon and then, come out to enjoy in the evening (about 4pm till as late as 12am mn). I find it difficult to adjust to this time schedule - somehow, feel more tired instead in the evening after the nap. And end up still requiring the 7-8hrs of sleep at night. Just cant go on till late at night (with afternoon nap) and still wake up at 5am tmrw.

Perhaps, the only time I can do this is on Thur nights as Fridays and Saturdays are weekends.

Any advice? : ) Andrew
