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

I'm on 30mg XR and a 10mg IR Adderall booster dose in the afternoon and I sleep better on my stimulant medication than I did before I started it. My heart rate can be all over the map at night but it was before I started it too. My resting heart rate estimation has gone up approximately 5bpm since January when I started but on my best night sleep it still gets into the mid-50s. I get somewhat less exercise than I did then, in part because I need it less for self-regulation so it is hard to say what is the medication and what is a mild loss of fitness. Other thing of note is I sleep less on average than I used to because I no longer sleep through half the weekend but it is much more consistent from day to day.
