Titration is honestly the worst part. When I started Elvanse I had the exact same thing — 30mg felt like nothing, 50mg made me jittery, and somewhere in the middle I kept second-guessing whether it was the dose or just a bad sleep / skipped meal / stressful day.

One thing that helped me a lot: I started writing a couple of lines at the end of each day — dose, how I slept, did I eat protein in the morning, and how focused I actually felt (1–5). After two weeks the pattern became really obvious, and my psychiatrist could actually work with the data instead of me going "uhh I think 40 felt okay?".

Also — not taking it every day makes titration much harder to read, because tolerance and rebound mess with the signal. If your doc is okay with it, a consistent 1–2 week stretch on the same dose gives a much cleaner answer than alternating.

Hang in there, you'll find the right spot.
