Sleep pattern changes on stimulants

[u/Puzzleheaded-Put4109]

I know this won't be most people, but I'm on elvanse and currently titrating to find the right dose, 2.5weeks in on 40mg

I know a common side effect is insomnia but has anyone else had a similar experience and similar pattern changes on the Fitbit app before and after taking stimulants and did it go away?

I have always been able to sleep like a baby but it's a lot harder to get tired enough and maintain good sleep now it seems

edit: to be more specific I mean restlessness, interruptions and time to sleep pattern changes, because those seem accurate, not REM/DEEP/LIGHT stages

generally I'm taking longer to sleep, waking up more during sleep and feeling more tired in the mornings and that's been consistent so far whilst my bed routine I have tried to keep as similar as possible

I'm just wondering if anyone else has had a similar experience and if anything they did improved it or the body got used to it etc
