amphetamne VS Methylphenidate. Has anyone experienced this?

[deekyleeky]

Ok so SWIM loves adderall. Very eurphoric, keeps me focused, and just all around a good drug, however, swims friend had some ritalin, he tried it, and just felt very anxious, and really anti-social. HOWEVER swims other friend had some concerta 54mg, he told me to break 3 in half, and you will be spun for several hours, almost like a really good meth high, but swim was reluctant to do so as he knew methylphenidate was the main ingredient, but he thought, eh whatevr, so he crushed and took, and let me tell you, he was right and then some, SPUN LIKE NO OTHER, never ever felt that from adderall or even meth. He was gona for a good 10 hours, come down= hell
Does anyone else have experience with this comparison.
