i almost wish i was more into downers, cause then i wouldnt have long sleepless nights and groggy day-afters where no matter how much more speed you do, you still feel like absolute shit. true, its cheap, euphoric as hell, and helpful for work and studying, but the physical and mental aftereffects really make it hard to tell whether the crash is worth the high. it feels like poison flowing through your body, melting everything it touches. unfortunately, some part of my brain is completed when i take stimulants, and they fix a lot of my problems with ADD, social anxiety, confidence, depression (until a few hours in), and general laziness. it quiets my restless thoughts in such a way that i can sit down and write a paper without wandering off to the kitchen everytime i try to maintain attention on my work for more than 45 minutes. the only reason im not addicted to it is because everytime i crash, i feel like such shit that i have to wait a long while to recover before i can use it again.
the only problem is that opiates tend not to impress me all that much, unless i IV them, which i wont do again. they are an interesting drug class though.
in general, though, im a polydrug user who was unlucky enough to have access to all manner of stimulants, but not much else. if my drug diet were more balanced i feel like i wouldnt have such a love/hate relationship with meth and stimulants.
