long ago at the beginnin' and for some time after i was extremely stressed and tired; at the end of the session i just collapsed and found also very difficult to sleep...now no more, altough i am pretty much torn apart after the closin' bell, i feel ok and sleep very well...i also trade asia overnite sometimes, without gettin' exhausted...but yeah when u have big positions on and things dont go that well it is extremely tiresome.
