Hmmm my brother has ADHD as well and we took him off his meds (he became very aggressive and had temper outbursts) and my stepdad would treat him more like a little child the more he misbehaved (put him in a corner for a couple of hours, couldn't sit, or lean on the wall, or made him write on a piece of paper.. i will not... yada yada.. 400 times or so). I dont know if this is "creative" but i know what you're dealing with and that's how we dealt with him. (We also took away his electronics and kept him in his room all day w/ only potty breaks and he had to eat dinner in his room alone)...there may be websites that could help you find something more "creative"... sorry i couldn't be more help !
