first of all... buying a pill of speed and taking meth are two very different things... on speed you feel clear headed and you are clear headed, on meth you feel clear headed but you are psycho. you do things you dont realise you're doing but you really think you know whats happening cause you just feel so fucking sane. i have a lot of friends who have become meth heads and trust me they do not know whats happening, and they frequently get into extremely outragous and ridiculous yelling at the top of your lungs and not remembering it the next day kind of things. the first time i took it i was sitting in a corner shaking for hours and ppl were telling me this while it was happening trying to calm me down but i yelled at them and called them crazy.. i thought they were trying to attack me. i didnt remember anything of what really happened, just replacement memories and i was up for three days wanting to kill myself as well, this stuff is SHIT and it made all my friends PSYCHO. ive never seen such fuckt up ppl in my life
