My buddy went on a real bender this weekend. It wasn't just his usual coke binge, he started off friday morning using opiods and benzos, then by noon he was drinking liquor, and then he got into his coke about 3 a.m. when the party started to wind down. He stayed up until sunday at noon doing coke and drinking before he crashed.
