not really.
ever have a period of time in which you drink coffee every morning, or at least habitually some mornings?
honestly, other drugs aren't different. to be truthful, i've done meth twice: one line a friend gave me, in two separate sittings. i'm a person who is lucky enough to be able to smoke a cigarette or a cigar once a month or less and not get addicted to nicotine. it's a blessing. the thing that i can't say no to are opiates. if you give me a botle of vicodin i will abuse it until it's gone; thus i've learned to stay the fuck away from them because i can't say no and it's debilitating.
knowing about yourself, and knowing how you react to things, and knowing your limits, cannot be a bad thing. i lived through all my experiences, and from what i'm inferring from your post, i'm assuming you're inferring the wrong things from mine
