ok, han, maybe my question may have been answered before.
i am helping a friend in newspaper distribution nowadays. this job requires me to wake up at about 3.30 am. i have great difficulty. i tried sleeping earlier, say about 9.30 pm, but i still have to drag myself up at 3.30am and depend on two alarm clocks.
is there a way to train my body to sleep earlier so that i have enough sleep and at the same time wake up at 3.30am?
