yes... my body very strange one... let's say i sleep at 11pm, i
WILL wake up at 5am the next morning. 1115pm, then 0515am...
many times liao, i set alarm clock for six hours after i sleep, and
i wake up 1-2 min before the alarm clock rings, all wide
awake.
of cos, there will be times when i will forced to sleep less than 6
hours, in which case i need to make up for it the next night.
Anyway i read somewhere that the human body works in 3-hourly
cycles, so if u sleep, try to sleep in multiples of 3 hours... 3,
6, 9 or 12 hours. u get more rest sleeping 9 hours than you do 8 or
10 hours... something like that.
