Jesus, good luck with that man.
My son has ADD. He took Ritalin all through school but stopped taking it his senior year. He's 34 now. The problem we have now is his addiction to meth. He says the meth doesn't affect him like others. He says it has the opposite effect on him because of his ADD. I think it's bullshit because I do see how it affects him. He will sleep for 15-20 hours coming down. I don't know if Adderall would help him, but it would be worth a try. He doesn't have insurance though. The other is destroying our family.
