I HATE Methylphenidate. Every time I've taken it I've had tightness in chest, pains, headaches, sweatyness, rapid heartbeat, anxiety, shakes.
I have a tolerance for amp and other stimulants, but Ritalin just fucks me up bad....
Oh and second most disgusting drug - Crack - The high feels like a minute of feeling good, the rest of the time wanting to try to get high and being excited to do it.
The only thing I ever found crack useful for was sitting with a 10$ fat bag of rocks that my friend stuffed full when he was selling, gave it to me as a gift. I sat watching porn at home taking hits.
I really hate the feeling of jerking it, then hitting the pipe, and being into the porn and masturbation but also the smoking and worrying about getting a good enough hit without burning my hands or lips and still being able to jerk it while high....out of all dilemmas in my life I never wanted one to be "should I take a hit then proceed jerking or jerk, then hit, put pipe down somehwere it won't burn my bedsheed and finsih jerking..
