Atomoxetine
"Strattera definitely helped my adult ADD, and increased my focus. However, it does have a downside, a few actually. Male erectile dysfunction, sweating, rage (but I think now that I'm bipolar, depressed which may be causing it).
You will definitely be able to focus better if you have minor ADD, but you will find that you can't sleep at night without a sleep aid (on Lunesta now). So the side effects are there, but it does do what it says it will. I'm going to try combining it with Pristiq and Lamotrigine to see if that is a good combination for the ADD/Bipolar/Depression."
