To add to the splitting thing, it says very specifically in my elvanse panphlet that you shouldn’t split it. Even if it didn’t I would be very difficult to split such a tiny dose of powder accurately, and getting a consistent dose everyday is important.
I take the same dose as you, and like you I felt it was a bit much on the first few days. Your body takes some time getting used to them, after two weeks 30 didn’t feel like too much anymore. It feels just right, it raises my heartbeat a bit 2 hours after I take it, and a bit later it evens out.
In my head it does not exist. Never trust myself to remember anything, write everything down in a system you trust (TickTick for me). In the same vein when leaving tasks halfway I write myself what I had planned to do next and all the details I can quickly jot down, even if they seem obvious or like I won’t forget them.
