And yes, both Ritalin and Adderall both made me nervous because of what I'd heard.
I tried it for a while several years ago, and, while it worked wonderfully (first period of my life where I actually had any reliable sense of time!), the side effects I had were unacceptable.
The mild dizziness, occasional headaches, and minor dry mouth were not a problem, but the main side effect was ... more troubling. Let's just say that, while the Strattera enhanced performance in some areas, it degraded performance in others.
Still, I heartily recommend those diagnosed with ADD or ADHD to give Strattera a try. Side effects went away within a week or so of discontinuing the drug, so no real risk.
I have non existent concept of time, so this might help.
I take the 100mg dose.
