Well, either your story is made up, or your doctor is a complete and utter moron... When you sit around not paying attention in class, that is not ADHD, it is ADD (that's ofcourse if it's anything at all, and has gone above and beyond the normal everyday behaviors of a kid...)
And the swift kick in the ass, leather strap crowd needs to get their facts before spouting off...
I do admit I cannot remember every single detail. Heck, it was almost 20 years ago and I was just a kid at the time being told all kinds of medical technobabble that I didn't understand. I would need to talk with my parents to get the exact details. I do know the drugs made me sick and could have killed me had I not stopped taking them.
