The thing about drugs is that you keep needing more. I bumped up my Adderall intake from 10mg to 15mg. I'm prescribed a full twenty, which would currently be absurd. At first when you increase, the dividends are huge. I have been an unassailable robot for a week. Eventually, however, it all evens out. You're back where you started, but worse. Take a little bit more, and a day off gets more sluggish.
For the time being, none of that is a problem. It's only another item to be aware of. I make a list of such items on scraps of paper. I keep my papers in a roaring fire pit, and bury the ashes deep underground.
