I shut myself in the study with a giant german beermug full of coffee or tea.
light my hubly (no weed)
then either:
a) spend the whole night reading a good book. Prefrably a nice gory one like S. Ericson.
b) play some pc games. Cant kill myself while i stil have a damn hard level to finish. Also, cant kill myself while there's stil some 10 year old korean punk who's ass i need to kick with a sword.
This is my ritual of distraction.
