We have had some similar issues.
Adderall works really really well, but rebound is definitely not pretty and didn't seem to deal iwth underlying depression.
Lamictal really helped, and a small dose of Risperdal seems to have helped the aggression and rebound.
My child would be lost with the stimulant, but he really needed something else. You can tell when the stimulant kicks in---cooperative, talkative, pleasant...
good luck. some medication changes might help.
