every day, without fail? my longest streak for heavy drinking is ten days.
i used to smoke pot everyday as soon as i woke up, all the way through until i went to bed - that went on for months, but i can't honestly remember how long - and there would be the occasional break if i had to meet family or something. there was quite a lot of drinking, coke and mdma involved during this time too.
as for worst single binge? that would be when i drank until the bars shut, wondered over to a junkie friend's house and ended up doing mdma, heroin, pot and vallium all in one night.
