This happens to my pet iguana every week:
1) Spend all day Friday fiending at work and looking forward to starting the weekend.
2) Leave work, call sdealer. Meet dealer at his place and buy at 3 gs
3) Gets home, takes off his suite, puts on a hoodie (he's a little weird in that he has certain cloths he loves to do coke
in), find some porn on tv, open a beer and gathers his "paraphanalia:" credit card, mirror, straw. Get sweaty palms and huge erection thinking about what he's about to do and paces around hisapartment.
4) Makes ackward small talk with dealer
4) Takes one bag (1/2g) and dump it ALL out on his favorite mirror
5) Uses his credit card to crush up all his coke and spends a few minutes chopping it up to make sure its super fine.
6) Seperates about half his pile into 4 big lines, leans over, snorts them (one each nostril). Leans back and lights a cigarette.
7) More pacing
8) In about 15 minutes does the rest in 4 more big lines. Feels extraordinary, totally numb face, his teeth are numb, he can't sit down and is now chain smoking.
9) Gets online and starts trying to see which of his coke buddies want to party. Watches lots of porn. Masturbates intensly. Meets up with friends and guys he finds online and has awesome coke sex. Takes many coke walks (especially when its cold...my iguana loves walking around his city coked out of his mind on really cold nights).
10) Panics because he's running low, its 6AM and he can't get to his dealer.
11) Repeat until Sunday night.
