Well hello JonB
The bad thing in this type of medication is the side effects you may or may not have them.
These are the ones that pertain to your question:
restlessness
difficulty falling or staying asleep
insomnia
agitation
tiredness
It's funny these are just a few, but lot's of them just clash
***Like tiredness, but you may have difficulty falling asleep and staying asleep, which can make you restless, which may make you agitated ***
The medication does eventually wear off by the end of the day. So hopefully these won't effect you.

I have ADHD and BP with other DX as well. I'm on Lamictal, Trileptal, and Concerta. I tried the Adderrall but IMHO-it really didn't seem to work to well for me. I am on 72 mg of Concerta. I am focused, but by the time it wears off 8-12 hours later. I get extremely Anxious. I have Sev. Anxiety as well but it kicks in bad later in the day, because the Concerta is wearing off. IMHO-I would try the Adderall, but maybe mention the Concerta to him. They both do the same thing really.
The doses just run differently.
The Concerta runs 18mg,27 mg, 36mg and 54mg tablets
The Adderall runs 5mg,10mg,15mg,20mg,25mg, to 30mg tablets.
Maybe it would be easier to monitor you on Adderall because of the dosages

I hope this helped you out a bit. I didn't mean to babble on. I have a tendency to do that. So I apologize.

Jlove
