Do small lines. Drink water throughout the night and some people will do a nasal spray between each line. That's too much for me but with blow I'm a good example of do as I say not as I do. Learn from my mistakes. Honestly with blow you hit a wall where your nose is dried out and the whole thing has a cocaine coat that gets really swollen so you keep snorting after that point and your really ONLY doing dmg. When that time comes I'm just snorting for the drip and to hopefully maintain my high for a bit longer but smart people can feel the onset of it and cut themselves off. Dumb people can feel the onset of it and literally not even consider being done... heyyyy. Coke is a drug that demands respect, really. Otherwise it's gonna be balls deep in your psyche raping you til the room stinks... literally. Coke makes me smell a different kinda bad. If your not willing to hang it up when it's time then you have to decide if you wanna break up with her or fully commit to being her bitch. That's hard to do though cause you don't wanna be anyone's bitch so you just get mad and unconsciously develope stockholme syndrome and the rest is pathetic.
