vyvanse | ADHD Information

My son is 7yrs old. We just stopped 20mg adderall xr and 10mg ritalin in the afternoon to 50 mg vyvanse. It seems to not be helping but keeping him up late. He takes clonidine and that take 3 or more hours to help as before maybe 1-2hrs. Any suggestions for getting him to relax for bedtime. what are your experinces good and bad with vyvanse?

how long has he been on vyvanse?  i had some insomnia as well at first but about mid second week it subsided......

He has only been on it for a little over a week.We use Melatonin over the counter with vyvanse and zoloft in am. it works great for my son 9, going on about 8 months?
