"i have bipolar disorder. 11 months in year major depression and 1 month mania. no any laugh in my life. after 7 years i tested just 10mg of ritalin and my life changed. ritalin make me happy. 20 mg 2 times in a day is perfect dosage for me. but i am not suggesting ritalin for all bipolar patients, because of the risk of mania.nobody  likes hospitalization.
it is better to inform your family that you intend to use ritalin."
