I agree eating right and exercise makes a huge difference and is working well enough right now by taking meds every other day and making sure that on those days I follow a good eating and exercise routine because it will help carry over the habit to the next day--not always, but most days.

My problem taking a smaller dose is that it puts me to sleep. I sometimes split my original dose to use as a sleep aid because I get great sleep on it. Falling asleep on adderall was not fun to tell my doc or the pharmacist when I first started on adderall. I was recommended for more screening. It still makes me tired for 10-15mins as the first dose kicks in.

Lighthearted is a good word to describe the differences I feel as well. Though I am quite hyperactive, maybe they are related--bouncy and lighthearted off and matching the calm of the Vulcans on them.
