i have ALOT of experience with drugs, whether prescription or illegal. Most experience with pot and fungi. Im diagnosed with ADHD and its not your everyday case of ADHD. I have some serious problems ADHD wise. Over the years ive been prescribed concerta, adderall, vyvanse, and most recently straterra( only non amp based med). Im in high school so of course i give my meds to friends sometimes( and i dont need to be lectured). Anybody who ever took my adderall or vyvanse would be completely wired and what i would call "twacked out". the users always told me about euphoria and energy and feeling like there on a roll(ecstasy). When I take these amp based med's it has a totally reverse effect on me, it makes me lethargic, extremely tired, non talkative. Even when I railed like 90mg of adderall IR i still would NEVER get a buzz. just focused and tired. or course when I tried to sleep I never could. It always pissed me off that I couldn't abuse these drugs but i guess its a good thing. recently I tried coke on a few occasions. while my friends were getting fucked up i did almost a 20 to myself and felt nothing, just a numb throat and nose. same thing when I did coke on 3 other occasions, not even a slight buzz that i can remember. now today my friend gave me a .5 rock of some pure crystal. i've seen them do the same shit and get twacked the fuck out. When I busted 5 so-so lines all i got was a little buzz and felt more not awake than before. it wasn't anything as i had heard it was. i kno FOR SURE its quality meth. im going to smoke another .2 sack i got today juss to see if the results repeat themselves. Someone please explain why ALL uppers do not affect me like anybody else. i believe maybe its due to my ADHD and the chemical inbalances in my brain...idk you tell me. anybody else ever experience this?
