Is being able to sleep after taking a stimulant like adderall a good indicator of whether or not you have ADHD?

I'm interested in the responses to this as well. I'm newly diagnosed and have been on Ritalin for a few weeks, having increased my dose gradually till 60mg/day currently. I'm having a hard time telling if it's doing anything for me. I know that meds don't solve everything but apart from some minor initial nausea and now at the higher dose my hands and feet get cold easily, I... still feel exactly the same as I always have. So I kind of got to wondering if I'm just immune to Ritalin or some nonsense and this morning just to see if I could I got out of bed, took my 20mg, got back in bed, and succeeded in falling asleep for another couple hours pretty easily. Curious to see any insights to if that's evidence for me needing to try another med or if I'm just really bad at waking up in the morning.
