Almost nocturnal? Well, the body will initially try it's very
best to adjust to the newly timed biological clock... though at
first, it may be hard, as you may suffer from symptoms of
sleepiness, slowness but eventually succumb to symptoms of
insomnia, wariness and alertness. Adjusting the whole biological
clock is not a one day's job to allow you to feel comfortable over
it, but amazingly our body is able to do it, over a few
weeks.
This also explains why certain ppl migrating to different time zone
will also experience such symptoms.
