No effect.: Ritalin (methylphenidate) affect is essentially cleared in less than 24 hours, depend in dose and extended release forms. Your symptoms are more suggestive of anxiety or panic attacks, but you should see a doctor to evaluate for other causes such as cardiac arhthmythia, anemia, hyperactive thyroid.
