"i am an adult female. i was prescribed 10 mg once a day. my counselor advised my behavioral health md to treat me for possible add/adhd. i&#039;m also taking clonopin and ambien, which might account for my reaction- ritalin made me sleepy and kind of depressed! i was really surprised, as i&#039;d never heard of that reaction. also taking lamictal and trileptal for bipolar. hm.... i sure would like to know if others have this reaction, or if upping the dose would possibly make me not so depressed."
