eventually u get used to coming off it. i actually don't mind it cos it's the only time i'm motivated enough to clean my room! but if u've been using for a couple of days & haven't slept or eaten much- then it's a real bitch! the gritty eyes, scattered thinking patterns, sensitive & hot skin, sore muscles,
indecisive-ness, deep voice, mutiliated mouth & swollen tongue, the list goes on... & on...
personally i don't believe in using more drugs to conteract whatever u have already taken. you made the choice to take it, you had the fun, so yeah... u suffer the consequences. if there were no consequences we would all abuse it & never stop.
this may sound stupid but it's important to have respect for whatever your using. if u don't respect it & what it can do to you(good or bad), you usually end up abusing it.
& yeah trust me 5gms isn't that hard or painful to do in one night. it isn't a good thing to be doing & probably should be ashamed of it... but yeah it's possible.
as far as i know or have experienced, the only long term differences between snorting & taking orally is the damage you do to your nose, sinuses etc. & i find snorting on a regular basis tends to destroy your gums.
