Effects - OMG the numbness

[flashcash]

hi, swim's been doing coke for a few months now. he got seriously hooked after the first few weeks but now he keeps it as a weekend thing.
theres something strange about swim's love for cola: he loves the numbness, not the high itself, actually he hates the speeding heart and comedown. over the past few months SWIM had a few batches of high quality little-numbing coke and he hated it, on the other hand he had lots of medium-to-low quality coke with great numbing effect and those were his favourites batches.
lately swim only does blow a few times a month and the usual trip is:
-lines
-cigarette
-masturbation
-cold shower (blow makes swim sweaty and feel dirty)
-lines
-cigarettes
-maybe more lines if swim cant control himself
-cold shower
so, basically swim does coke just for the numbing. it makes smoking cigs feel so good!!!
Its swim just a crazy fucker or does anybody else loves the teeth and face numbing but not the high itself???
swim always wonders where he could get some kind of anesthetic powder, like the kind they use to cut the cola.

btw: swim always reads about folks who do massive amounts of blow and get their faces or heads numb. how much coke would it take to do so?
