I know that you live in Europe... your polish and you live in Poland or something like that... I'm from Europe as well... Moved to Italy for a 2-3 years vacation so I can write my new books and trading in the rest of the time... Sleep is a bit weird, but all is fine in Europe, everyone clubbing till morning everywhere, but is good that I live in the suburbia, ambulances and fire trucks not bothering me that much.

*Edit: That DaRude guy also has weird sleeping hours... He probably trades as well.. 100%.
