Can’t sleep after only morning IR dose

Is this normal? I got started on 5mg adderall twice daily (9am/2pm) and it had no effect on my sleep, and when I went up to 10mg the 2pm dose would make sleep very difficult, now I’m on 20mg in the morning only and I cannot sleep at all. Will this improve with time? (today is the first day on this dosage)

All my life I’ve had issues going to sleep, even as a little kid. In the past I’ve tried hydroxyzine and it didn’t help, remeron which stopped helping, trazodone which plugs my nose the whole night, and zyprexa which I’m currently on that also stopped helping with sleep. What are my options for a good sleep aid? Also open to supplements, I take 1000mg magnesium glycinate which has no noticeable effect on my sleep, melatonin also does basically nothing.
