What a strange life style. I only have an alarm clock so that I can keep
my eyes closed till the last minute. I am always awake beforehand.
Perhaps, if I were to attempt getting up at an odd time (currently, I go
for 5.30 am), then your method might be appropriate, although I have
never had problems with waking at 2, 3 or 4 am when required. My body
clock tells me to wake up.
