Looking for some tips from the better-living-through-chemistry set. I'm a writer and was having trouble getting anything done; my doctor put me on Adderall but not a big dose: 10mg 2x daily. At 6'2" 205lbs. this is apparently not much, but the effects were fucking seismic; I was writing my balls off. About 6 weeks in, though, the effect became much more mild. He has since bumped me to 15mg 2x daily, and it's again pretty great, but I'm concerned that I'll just keep adjusting and needing more and more.

Are there any tips you can share to maximize the effect of the dosage I'm at or anything else useful that you have learned? Is it better to take it as infrequently as possible, or does it have the most stable effect by being rigor about the 2x daily? On days when I'm not going to write, I tend not to take it.
