Honestly? I supplement my adderall with caffeine. I've found that some of the "brain" multivitamins work ok. There are B vitamins. Not just B12, but if you get one, get complete B. Vitamins. Out of all the energy drinks, the Starbucks Doubleshot helps the most with no side effects. You might have to experiment, which ones work best for you. A Starbucks, mixed with a Carnation Instant Breakfast shake could keep me going all day when I worked my 10hr shift. Your brain needs more sugar than the average person, so sipping on juice or some hard candies throughout the day will help also.
