ADHD
"I went undiagnosed with severe ADHD for 20 years because another problem was complicating the diagnosis.  I had been taking various energy drinks in an effort to concentrate.  Just a few days ago, I was given a prescription for Nuvigil.  

Wow.  This stuff hit me like a mac truck! It was unlike anything I have ever experienced.  For once, I actually had the drive and motivation to organize things and get things done.  

I immediately proceeded to straighten every single thing in my room, down to the last bits of lint on the carpet.

I like the new me.  I hope it lasts."
