Hey, Ryo, I just had a thought, and I was wondering how you wanted to handle it.
I double checked both my PDF and my OOC post of Thorn's character sheet, and I don't believe he's taking meds for his ADHD. Most ADHD medicine are actually stimulants, so could I role play him as being more calm and collected when on cram? He's still mildly addicted to cram of course and will eventually have to roll for it.
I could even say he's self medicating if you're ok with the idea I had. I think that this fits Thorn pretty well by not wanting to be hooked into going to the man every month to get his meds. I thought that'd be a fun (and accurate) direction to go, but I wanted to see how you felt about it. If you don't like it, then I'll just go with how the book lists it. (Thorn wouldn't get a bonus to his Illness roll from the cram because while it helps its obviously not the correct medicine or right dose that he actually needs)
Jazz would definitely make him jittery and jumpy, but I think maybe not quite to the degree its described in the book. Kamikaze wouldn't change at all.
