For the record, ADD doesn't really exist anymore. It's ADHD with subtypes inattentive, hyperactive, or combined inattentive and hyperactive.

I'm inattentive. About once a year I decide to try to go without medication for a month, but it's too hard. I've done mindfulness exercises, tried to focus on developing new habits, etc... but medication works best. A combination of concerta and wellbutrin works best for me, because I can take lower amounts of the stimulants and wellbutrin has less side effects for me. I was on adderall for a few years, but headaches + sleep stuff made it more annoying as time went by.

I got diagnosed when I was 20 by a family practitioner, when I decided I was having problems with focusing (physics major). after a few years of that I decided he was shit and I needed an official diagnosis and a psychiatrist to sort it all out, someone who knew about the disorder and medications. We tried Strattera, which worked awesome except for the "sexual side effects" which were too weird for me.

Friends can tell when I'm on or off of it. Colleagues can't, although I'm conscious of my decreased work.
