ADHD
"I was diagnosed with ADD as a child and had been prescribed several medications including wellbutrin, nuerontin, and metadate. All proved ineffective (and the wellbutrin Damn near killed me). Finally I was introduced to Adderall. Adderall finally helped me focus while elevating my mood. I even became friendlier, because I was no longer frustrating myself trying to find the words I wanted to say. 

The side effects were mostly mild and went away once the medication built up in my system. Dry mouth, fidgeting, mild erectile dysfunction.

Vasoconstriction was the only side effect that tended to linger, and I recently discovered the hard way that if you are experiencing vasoconstriction, it is wise to avoid heavy exertion."
