Amphetamine / dextroamphetamine
"I am reading different ADHD meds affect ppl differently. I see ppl posting that the same mgs meds from different manufacturers have varying potency. I was an ADHD child. I am now 56 y/o. I started taking Concerta (long acting ritalin) 56 mg from 2007 to 2014, then a new dr wouldn't prescribe it for me in 2014. It was a miracle drug. It gave me energy, strength, focus, avid concentration, a positive mood, goals and hope. Now, I have been off ADHD meds for 2 yrs. I gave it time to see if I could get better without it. It's getting worse. I stay in bed, don't shower, no motivation. Drs fear addiction 'coz of my age. I can't go on as a vegetable. Off the meds I grind my teeth like mad. I am gnashing my teeth from aggravation and lack of focus."
