this isnt exactly a scientific response, but from what i've observed amongst friends and acquaintances using meth over the years, it would seem to me that it is the extended, multi-day benders that do the most harm.
in my days of using (which were fairly considerable but nowhere near as bad as some) i only got the the third day of abuse on one or two occasions. and while i've heard meth heads say much to the contrary (ben cousins being a very public example), i thought it was horrible.
if you are interested in dabbling with methamphetamine and not affecting your long-term mental health and neurological wellbeing, i would strongly suggest avoiding a deliberate multi-day bender. if it ends up happening, that's cool, but i don't really consider it to be the next thing to try, the next boundary to push.
i'm not one to lecture, but in the harm minimisation context - it pays to respect your body, man!
i feel like i emerged from my years of playing with meth pretty much unscathed, unlike a lot of my friends.
i put this down to the fact that i didn't completely overdo it in the sleep deprivation stakes. sleep is vital to your body's functions, healing and repairing.
stimulants make you feel like you don't need sleep (and prevent you from getting it) but they don't stop you from
needing sleep.
as i said, this isn't a scientific response, just what i have felt and observed.
you seem to be doing this with your eyes open and with full attention to inherent risks...
it doesn't seem worth it to me.
the high is better when you're fresh, and the longer you go, the more you wear yourself out and take more from your body than it has to give you. when you've been up for a night or two, you get frazzled, scattered, and you need to keep re-dosing in order to focus and function.
this might be part of the cycle of methamphetamine use for some folks, but i get bored spending hours compulsively doing repetitive tasks with all that fucked-up neurotic energy, waiting to come down or have another hit.
all-nighters are par for the course, but multi-nighters are where you start slipping into 'abuse' territory IMO.
also, i don't think dreaming about drugs is necessarily unusual or a problem.
i dream about drugs all the time, but this doesn't mean they are central to my thoughts or that i am some kind of dope fiend (*ahem*)
it's certainly a stretch to say that if you're dreaming about having a shot, that you're doomed to become a homeless junkie or something. the subconscious can draw on any number of things when you are dreaming.
i bet footy jocks dream about rolling around in the mud with men in little shorts - it doesn't mean they're homosexual. it just means they think about football enough for it to enter their dreams.
