When giving a over effective dose of stimuli the adrenals get overloaded causeing a drowsy calming sleepy effect, thus why it is prescribed to kids with ADHD, for this effect alone, legalised speed for children !!!
It is total bullshit, my nephew apparently suffered from ADHD and was on the stuff for years , he came to live with us as he was having trouble at home , the first thing we did was take him of the Ritalin, and with kindness and attention he was pretty much normal in 4-5 weeks , he lived with us for 2 years and never went back on the stuff, his schooling improved ,his tantrums stoped and now he has a job as a apprentance mechanic and has never looked back !!!
Its all bullshit , the problem starts with the mum and the dads !!! !!
