ADHD with stimulant and non-rx sleep aids?

Hi, I'm sure this thread has happened before, but...We just adjusted Cricket's adderall and his days are awesome. He has so much control over himself and his self-esteem benefits. BUT, he is having increased sleep disturbance. Not walking or terrors or anything, just awake more often during the night and having trouble going back to sleep. I'm REALLY not looking to add to his medication regimen - I have enough reservations as is, evidenced my all the above justification - but I want him to be able to get good sleep. We already have a consistent nighttime calming routine with bath, stories, and lullabies. He has a nightlight and and anchoring stuffy. What else natural do you do with your kids on stimulants to help them get a good night's sleep that's natural? We're headed to the doc today, and of course I'll ask the professional, but she tends to be a little scrip-happy. I prefer this group of experts. :o
