how long you want to do this for ? I experienced it for like 4
mths ? kinda of draining on body and felt burned out by the end of
4 mths. it was work related.
i worked till ard 8pm,before heading off to the gym , then coming
back home to work till ard 2-3 am, before waking up at 8 am again
to go work.
the alternate days ( tues and thurs) were just straight till
2am.
However i had the saturdays and sundays off .so it kinda of
balanced off for me i guess.
But i had colleagues who were doing this for like 6-7 mths straight
it have a serious toll on their bodies,haggard faces, more tired
and prone to be ill.
