Do not do this unless u are experienced with this drug. so today i took 6 34mg concerta and holy shit i couldnt stop moving i bit my nails to nothing and bit my lips until they bled. i cant lie tho i liked the feeling of being sped up....actually i still am high just a little tho. first timers i recomend u not take 6 ur first time u do start to feel like shit after a while and get angry easily. but who am i to stop you shit take the whole bottle if u want jk lol XD
Ritalin and Concerta are both methyphenidate. Vyvanse is lisdexamfetamine. I prefer plain ol' amphetamine to all of those, personally.
