I guess the window for serious replies has passed. NCH gave one approach to stimulant use for ADHD folks and I just want to share another side. I actually find it unhelpful to only take medicine for prep-tests and so on. Stimulant medications, especially Adderall, give you a "rush" that I've only really found distracting and bad for my overall performance. I take Vyvanse every day (lower dose spread over the day) and it really helps. Remember, stimulants are a big part of our ADHD treatment but not the only one. I find that stimulants give me the push I need to get going on stuff and the nudge I need to stay on track. Getting a super-focused high might be helpful, it might not be, but try to keep everything in perspective. When you're finally working you'll want to be able to manage your ADHD day in, day out, not just on test day. Not passing judgment on anybody's coping strategies but I don't want ADHD readers to come away from this thread thinking they necessarily have to fiddle with their medication regiment for optimal performance. Some people might find that helpful, but I don't.
