Methylphenidate
"Been taking this for 2 months. I've tried nearly every other ADHD med. I take IR Methylphenidate 10mgs BID. Although it helps w/ concentration and motivation in my day to day activities, there are downsides.
Pros:
%u2022very cheap
%u2022 makes me feel the best, I genuinely enjoy learning and taking notes in class, among other things
%u2022helps w/ Social Anxiety Disorder, I'm more talkative
CONS:
%u2022Increases impulsivity (e.g. Online shopping, among other things)
%u2022depresses me, makes me more suicidal
%u2022terrible drop off when meds wear off, intense anxiety and depression...

Personally, side effects are too dangerous for me and outweigh the pros. Hope this helps"
