Hi Have 3 adult kids,all with varying degrees of AD/HD. My youngest is 19 and I've had to tell him he's not welcome at home until he can prove he's taking the necessary steps to get the help he so desperately needs. On dexamphetamine he's fine, able to function in the world. Without it he's out of control and his frontal lobe just goes down the plug hole! He's "dating" a 15 yr old!!!! So much more going on and just stressed out completely.
