First Post Methylphenidate question

[mirabella]

SWIM has been taking 30mg Adderall XR orally (unprescribed) daily for 2 months. SWIM has been given seven 20mg controlled release generic methylphenidate pills. SWIM assumes she now has a tolerance for adderall since euphoric period lasts less than an hour after dose and then adderall works as it is supposed to, making her more organized, motivated, and effecient. SWIM has no experience with methylphenidate. What dose and method of delivery will most likely induce a euphoria/speedy effect based on previous history? Also take into consideration it is controlled release; if necessary, what is best way to circumvent this mechanism for methylphenidate?
