I dont believe anyone planned on OD'ing, And what you described happens with alot of drugs when you OD, heart beating fast, sweats, shaking Im pretty sure people taking ritalin aren't taking it to "trip" either. Maybe I already do have a bag of dope, maybe I have some DXM suppositories in my back pocket.... maybe Im growing some mushrooms... but I want ritalin too. I gotaa have it all hahhh
