Damn..I could be wrong but snorting 8 bags at a time (and especially 'bags' of street dope and not higher purity dope) seems a lot worse on your body than IV. Do you know how much unneeded crap your putting into your nostrils? if you figure your dime bags have about 40% purity, that would means your snorting almost 5 bags of non-opiate materials.

I don't know what kinda shape your nose is in but my guess is in less than perfect condition..
Atleast when you IV you cook off a lot of the impurities. But if you are really against the needle and you are this deep in the habit I'd reccommend a nice body detox with some bupe or even xanax (you claim to not get that sick w/ the snorting habit so that may be doable) and get that tolerance back down.
