Anything that you have to qualify with "if presented properly, I could play it off..."
It wasn't a troubling experience, and you never had to overcome anything. If someone on an adcom has this condition, or knows someone who does, and this person had the same experience of minor effects and 1 pill everyday, then they're going to see right through you.
People who have overcome real issues and obstacles are challenged when tryign to write about it in a mature, non-whiney way. If you're jsut making stuff up, I can't see how you'd be able to pull it off.
And above and beyond all of this, it's just flat out dishonest.
