Nikki describes himself as having two personalities, one he calls nikki and the other he calls sikki. nikki is the normal person but sikki is his personality when he gets high. when hes high everything goes insane his whole life spirals into chaos and when he comes back down all he wants to do is get high again. nikki would use cocaine but then when he got too high his hallucinations got the best of him. he would quickly go to his heroin den and shoot up. eventually he would be so addicted that he would shoot up until his veins collapsed and he would shoot up in his neck his legs his feet and even his penis. vanity is his girlfriend she was a former dancer for prince and she even dated him for a while. nikki saw her on tv once and said she was hot so he called his management and told them to arrange a meeting and from then off the were two junkies in a syringe. the first time you use heroin you throw up and your head spins and you say to yourself this is the stupidest drug ever but nikki kept at it and now he gets sick when he doesnt have it. he does heroin because his heroes did it so why shouldnt he? heroin to him was like a warm bloanket on a cold night .
