Help please? what is it like to take 30mg ritalin (methylphenidate) pills to get a high?

Don't Bother: Taking 30mg of Ritalin (methylphenidate) will do little except increase your heart rate, elevate your blood pressure, and will not give a "high". Taking these kind of medicines without your physicians approval can be dangerous and should never be done. I list the mild effects, but long term use can lead to paranoid schizophrenic reaction that is very difficult to treat, don't bother trying!
